Give the conjecture the name *1.
We will appeal to induction. There is only one plausible induction. We
will induct according to the following scheme:
(AND (IMPLIES (ZEROP N) (p N))
(IMPLIES (AND (NOT (ZEROP N)) (p (SUB1 N)))
(p N))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP inform
us that the measure (COUNT N) decreases according to the well-founded relation
LESSP in each induction step of the scheme. The above induction scheme
produces the following two new conjectures:
Case 2. (IMPLIES (ZEROP N)

We will try to prove it by induction. The recursive terms in the

Linear arithmetic and the lemma CDR-LESSP can be used to prove that the
measure (COUNT L) decreases according to the well-founded relation LESSP in
each induction step of the scheme. Note, however, the inductive instance
chosen for K. The above induction scheme leads to the following three new

Name the conjecture *1.
Let us appeal to the induction principle. The recursive terms in the
conjecture suggest three inductions. However, they merge into one likely
candidate induction. We will induct according to the following scheme:

(p L K I J))

Linear arithmetic and the lemma CDR-LESSP can be used to prove that the
measure (COUNT L) decreases according to the well-founded relation LESSP in
each induction step of the scheme. Note, however, the inductive instances
chosen for J and K. The above induction scheme leads to the following four

Applying the lemma SUB1-ELIM, replace J by (ADD1 X) to eliminate (SUB1 J).
We rely upon the type restriction lemma noted when SUB1 was introduced to
restrict the new variable. We would thus like to prove the following
three new conjectures:

which further simplifies, using linear arithmetic, to two new goals:

Name the conjecture *1.
Let us appeal to the induction principle. The recursive terms in the
conjecture suggest three inductions. However, they merge into one likely
candidate induction. We will induct according to the following scheme:
(AND (IMPLIES (ZEROP N) (p L N I))
(IMPLIES (AND (NOT (ZEROP N))

(p L N I))
(IMPLIES (AND (NOT (ZEROP N))
(NOT (UNION-AT-N L N I))
(p L (SUB1 N) I))
(p L N I))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP can be
used to show that the measure (COUNT N) decreases according to the
well-founded relation LESSP in each induction step of the scheme. The above
induction scheme leads to the following four new goals:
Case 4. (IMPLIES (AND (ZEROP N) (EXIST-UNION L N I))

new formulas:
Case 5. (IMPLIES (AND (MEMBER J (NSET N))

which we will name *1.
Case 4. (IMPLIES (AND (MEMBER J (NSET N))
(EQUAL (NTH L J) 9))
(EXIST-UNION L N '(8 9 10 11 12))),
which we would usually push and work on later by induction. But if we must
use induction to prove the input conjecture, we prefer to induct on the
original formulation of the problem. Thus we will disregard all that we
have previously done, give the name *1 to the original input, and work on it.
So now let us consider:
(IMPLIES (AND (MEMBER J (NSET N))
(UNION-AT-N L J '(8 9 10 11 12)))
(EXIST-UNION L N '(8 9 10 11 12))),
which we named *1 above. We will appeal to induction. Two inductions are
suggested by terms in the conjecture. However, they merge into one likely
candidate induction. We will induct according to the following scheme:
(AND (IMPLIES (ZEROP N) (p L N J))
(IMPLIES (AND (NOT (ZEROP N))
(UNION-AT-N L N '(8 9 10 11 12)))
(p L N J))
(IMPLIES (AND (NOT (ZEROP N))
(NOT (UNION-AT-N L N '(8 9 10 11 12)))
(p L (SUB1 N) J))
(p L N J))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP
establish that the measure (COUNT N) decreases according to the well-founded
relation LESSP in each induction step of the scheme. The above induction
scheme produces the following four new conjectures:
Case 4. (IMPLIES (AND (ZEROP N)
(MEMBER J (NSET N))
(UNION-AT-N L J '(8 9 10 11 12)))
(EXIST-UNION L N '(8 9 10 11 12))).

(EXIST-UNION L N '(8 9 10 11 12))).
This simplifies, appealing to the lemmas CDR-CONS and CAR-CONS, and
expanding the definitions of ZEROP, MEMBER, LISTP, CAR, CDR, UNION-AT-N,
NSET, and EXIST-UNION, to the following 25 new conjectures:

We will appeal to induction. The recursive terms in the conjecture
suggest six inductions. However, they merge into one likely candidate
induction. We will induct according to the following scheme:
(AND (IMPLIES (ZEROP N) (p LP N))
(IMPLIES (AND (NOT (ZEROP N))
(UNION-AT-N LP N '(8 9 10 11 12)))
(p LP N))
(IMPLIES (AND (NOT (ZEROP N))
(NOT (UNION-AT-N LP N '(8 9 10 11 12)))
(p LP (SUB1 N)))
(p LP N))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP inform
us that the measure (COUNT N) decreases according to the well-founded relation
LESSP in each induction step of the scheme. The above induction scheme leads
to the following eight new goals:
Case 8. (IMPLIES (AND (ZEROP N)
(EXIST-UNION LP N '(8 9 10 11 12))
(NOT (EQUAL (NTH LP

Let us appeal to the induction principle. Three inductions are suggested
by terms in the conjecture. However, they merge into one likely candidate
induction. We will induct according to the following scheme:
(AND (IMPLIES (ZEROP N) (p G N L))
(IMPLIES (AND (NOT (ZEROP N))

Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP
establish that the measure (COUNT N) decreases according to the well-founded
relation LESSP in each induction step of the scheme. The above induction
scheme produces five new goals:

WARNING: Note that L34-EMPTY contains the free variables G and N which will

This formula can be simplified, using the abbreviations NOT, AND, IMPLIES, and

(NOT (EQUAL (NTH L J) 4))),
which we would usually push and work on later by induction. But if we must
use induction to prove the input conjecture, we prefer to induct on the
original formulation of the problem. Thus we will disregard all that we
have previously done, give the name *1 to the original input, and work on it.
So now let us consider:
(IMPLIES (AND (MEMBER J (NSET N))
(LG N L G)
(NOT (EXIST-UNION G N '(1))))
(NOT (UNION-AT-N L J '(3 4)))).
We gave this the name *1 above. Perhaps we can prove it by induction. Three
inductions are suggested by terms in the conjecture. However, they merge into
one likely candidate induction. We will induct according to the following
scheme:

We will appeal to induction. Two inductions are suggested by terms in
the conjecture. However, they merge into one likely candidate induction. We
will induct according to the following scheme:
(AND (IMPLIES (ZEROP N) (p G K L N))
(IMPLIES (AND (NOT (ZEROP N))
(p G K L (SUB1 N)))
(p G K L N))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP inform
us that the measure (COUNT N) decreases according to the well-founded relation
LESSP in each induction step of the scheme. The above induction scheme leads
to the following three new goals:
Case 3. (IMPLIES (AND (ZEROP N)
(MEMBER K (NSET N))

Perhaps we can prove it by induction. The recursive terms in the
conjecture suggest three inductions. However, they merge into one likely
candidate induction. We will induct according to the following scheme:
(AND (IMPLIES (ZEROP N) (p G N L))
(IMPLIES (AND (NOT (ZEROP N))

(p G N L))

(p G N L))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP inform
us that the measure (COUNT N) decreases according to the well-founded relation
LESSP in each induction step of the scheme. The above induction scheme
generates the following five new conjectures:
Case 5. (IMPLIES (AND (ZEROP N)

Perhaps we can prove it by induction. There are six plausible inductions.
However, they merge into one likely candidate induction. We will induct
according to the following scheme:
(AND (IMPLIES (ZEROP N) (p L N G))
(IMPLIES (AND (NOT (ZEROP N))
(INTERSECT-8-12-3-4-AT-N N L G))
(p L N G))
(IMPLIES (AND (NOT (ZEROP N))

(p L (SUB1 N) G))
(p L N G))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP can be
used to establish that the measure (COUNT N) decreases according to the
well-founded relation LESSP in each induction step of the scheme. The above
induction scheme produces eight new formulas:
Case 8. (IMPLIES (AND (ZEROP N)

which we would usually push and work on later by induction. But if we must
use induction to prove the input conjecture, we prefer to induct on the
original formulation of the problem. Thus we will disregard all that we
have previously done, give the name *1 to the original input, and work on it.
So now let us consider:
(IMPLIES (AND (MEMBER J (NSET N))
(LG N L G)
(UNION-AT-N L J '(9 10 11 12)))
(AT G J 4)),
which we named *1 above. We will appeal to induction. Two inductions are
suggested by terms in the conjecture. However, they merge into one likely
candidate induction. We will induct according to the following scheme:
(AND (IMPLIES (ZEROP N) (p G J L N))
(IMPLIES (AND (NOT (ZEROP N))
(p G J L (SUB1 N)))
(p G J L N))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP
establish that the measure (COUNT N) decreases according to the well-founded
relation LESSP in each induction step of the scheme. The above induction
scheme produces the following three new goals:
Case 3. (IMPLIES (AND (ZEROP N)

Perhaps we can prove it by induction. Two inductions are suggested by
terms in the conjecture. However, they merge into one likely candidate
induction. We will induct according to the following scheme:
(AND (IMPLIES (ZEROP N) (p LP N))
(IMPLIES (AND (NOT (ZEROP N))
(UNION-AT-N LP N '(8 9 10 11 12)))
(p LP N))
(IMPLIES (AND (NOT (ZEROP N))
(NOT (UNION-AT-N LP N '(8 9 10 11 12)))
(p LP (SUB1 N)))
(p LP N))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP inform
us that the measure (COUNT N) decreases according to the well-founded relation
LESSP in each induction step of the scheme. The above induction scheme
generates the following four new formulas:
Case 4. (IMPLIES (AND (ZEROP N)
(EXIST-UNION LP N '(8 9 10 11 12)))
(NOT (EQUAL (NTH LP
(EXIST-UNION LP N '(8 9 10 11 12)))

This simplifies, unfolding the functions ZEROP, EQUAL, and EXIST-UNION, to:
T.

WARNING: Note that IF1 contains the free variables G and N which will be
chosen by instantiating the hypotheses (MEMBER J (NSET N)) and (LG N L G).
This conjecture can be simplified, using the abbreviations NOT, AND, IMPLIES,
and UNION-AT-N, to:
(IMPLIES (AND (MEMBER J (NSET N))
(LG N L G)
(MEMBER (NTH G J) '(0 1)))
(NOT (MEMBER (NTH L J)

This simplifies, unfolding the definitions of CDR, CAR, LISTP, and MEMBER, to
the following 16 new conjectures:
Case 16.(IMPLIES (AND (MEMBER J (NSET N))
(LG N L G)
(EQUAL (NTH G J) 0))
(NOT (EQUAL (NTH L J) 5))).
Call the above conjecture *1.
Case 15.(IMPLIES (AND (MEMBER J (NSET N))
(LG N L G)
(EQUAL (NTH G J) 0))
(NOT (EQUAL (NTH L J) 6))),
which we would usually push and work on later by induction. But if we must
use induction to prove the input conjecture, we prefer to induct on the
original formulation of the problem. Thus we will disregard all that we
have previously done, give the name *1 to the original input, and work on it.
So now let us consider:
(IMPLIES (AND (MEMBER J (NSET N))
(LG N L G)
(UNION-AT-N G J '(0 1)))
(NOT (UNION-AT-N L J
'(5 6 7 8 9 10 11 12)))),
which we named *1 above. We will appeal to induction. Two inductions are
suggested by terms in the conjecture. However, they merge into one likely
candidate induction. We will induct according to the following scheme:
(AND (IMPLIES (ZEROP N) (p L J G N))
(IMPLIES (AND (NOT (ZEROP N))
(p L J G (SUB1 N)))
(p L J G N))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP inform
us that the measure (COUNT N) decreases according to the well-founded relation
LESSP in each induction step of the scheme. The above induction scheme
generates the following three new formulas:
Case 3. (IMPLIES (AND (ZEROP N)
(MEMBER J (NSET N))
(LG N L G)
(UNION-AT-N G J '(0 1)))
(NOT (UNION-AT-N L J
'(5 6 7 8 9 10 11 12)))).
This simplifies, opening up ZEROP, NSET, LISTP, and MEMBER, to:
T.
Case 2. (IMPLIES (AND (NOT (ZEROP N))
(NOT (MEMBER J (NSET (SUB1 N))))
(MEMBER J (NSET N))
(LG N L G)
(UNION-AT-N G J '(0 1)))
(NOT (UNION-AT-N L J
'(5 6 7 8 9 10 11 12)))).
This simplifies, rewriting with CDR-CONS and CAR-CONS, and unfolding ZEROP,
NSET, MEMBER, LISTP, CAR, CDR, and UNION-AT-N, to 16 new conjectures:

This conjecture can be simplified, using the abbreviations NOT, AND, IMPLIES,

following four new formulas:
Case 4. (IMPLIES (AND (MEMBER K (NSET N))
(LG N L G)

(NOT (EQUAL (NTH L K) 5))).
Give the above formula the name *1.
Case 3. (IMPLIES (AND (MEMBER K (NSET N))
(LG N L G)
(EQUAL (NTH G K) 4))
(NOT (EQUAL (NTH L K) 6))),
which we would usually push and work on later by induction. But if we must
use induction to prove the input conjecture, we prefer to induct on the
original formulation of the problem. Thus we will disregard all that we
have previously done, give the name *1 to the original input, and work on it.
So now let us consider:
(IMPLIES (AND (MEMBER K (NSET N))
(LG N L G)
(AT G K 4))
(NOT (UNION-AT-N L K '(5 6 7 8)))),
which we named *1 above. We will appeal to induction. There are two
plausible inductions. However, they merge into one likely candidate induction.
We will induct according to the following scheme:
(AND (IMPLIES (ZEROP N) (p L K G N))
(IMPLIES (AND (NOT (ZEROP N))
(p L K G (SUB1 N)))
(p L K G N))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP
establish that the measure (COUNT N) decreases according to the well-founded
relation LESSP in each induction step of the scheme. The above induction
scheme leads to the following three new goals:
Case 3. (IMPLIES (AND (ZEROP N)
(MEMBER K (NSET N))
(LG N L G)
(AT G K 4))
(NOT (UNION-AT-N L K '(5 6 7 8)))).
This simplifies, expanding the functions ZEROP, NSET, LISTP, and MEMBER, to:
T.
Case 2. (IMPLIES (AND (NOT (ZEROP N))
(NOT (MEMBER K (NSET (SUB1 N))))
(MEMBER K (NSET N))
(LG N L G)
(AT G K 4))
(NOT (UNION-AT-N L K '(5 6 7 8)))).
This simplifies, appealing to the lemmas CDR-CONS and CAR-CONS, and opening
up the definitions of ZEROP, NSET, MEMBER, AT, LISTP, CAR, CDR, and
UNION-AT-N, to the following four new conjectures:
Case 2.4.
(IMPLIES (AND (NOT (EQUAL N 0))
(NUMBERP N)
(NOT (MEMBER K (NSET (SUB1 N))))
(EQUAL K N)
(LG K L G)
(EQUAL (NTH G K) 4))

But this again simplifies, unfolding LG, LG-3-AT-N, EQUAL, AT, and LG-AT-N,
to:
T.

Give the above formula the name *1.
We will appeal to induction. The recursive terms in the conjecture
suggest two inductions. However, they merge into one likely candidate
induction. We will induct according to the following scheme:
(AND (IMPLIES (ZEROP N) (p L U G N))
(IMPLIES (AND (NOT (ZEROP N))
(p L U G (SUB1 N)))
(p L U G N))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP
establish that the measure (COUNT N) decreases according to the well-founded
relation LESSP in each induction step of the scheme. The above induction
scheme generates the following three new formulas:
Case 3. (IMPLIES (AND (ZEROP N)
(MEMBER U (NSET N))
(LG N L G)
(EQUAL (NTH G U) 4)
(NOT (EQUAL (NTH L U) 8))
(NOT (EQUAL (NTH L U) 9))
(NOT (EQUAL (NTH L U) 10))
(NOT (EQUAL (NTH L U) 11)))
(EQUAL (NTH L U) 12)).
This simplifies, opening up the definitions of ZEROP, NSET, LISTP, and
MEMBER, to:
T.
Case 2. (IMPLIES (AND (NOT (ZEROP N))
(NOT (MEMBER U (NSET (SUB1 N))))
(MEMBER U (NSET N))

(NOT (EQUAL (NTH L U) 9))
(NOT (EQUAL (NTH L U) 10))
(NOT (EQUAL (NTH L U) 11)))
(EQUAL (NTH L U) 12)).
This simplifies, applying CDR-CONS and CAR-CONS, and expanding ZEROP, NSET,
MEMBER, LG, LG-3-AT-N, AT, LG-AT-N, and EQUAL, to:
T.
Case 1. (IMPLIES (AND (NOT (ZEROP N))

which simplifies, rewriting with CDR-CONS and CAR-CONS, and opening up the

WARNING: Note that LP9-12-THEN-K-IN-G34 contains the free variables LP and N
which will be chosen by instantiating the hypotheses (MEMBER K (NSET N)) and:
(UNION-AT-N LP K '(9 10 11 12)).
This conjecture can be simplified, using the abbreviations AND, IMPLIES, and
UNION-AT-N, to the formula:
(IMPLIES (AND (MEMBER K (NSET N))
(MEMBER (NTH LP K) '(9 10 11 12))
(LG N LP GP))
(MEMBER (NTH GP K) '(3 4))).
This simplifies, expanding the functions CDR, CAR, LISTP, and MEMBER, to the
following four new formulas:
Case 4. (IMPLIES (AND (MEMBER K (NSET N))
(EQUAL (NTH LP K) 9)
(LG N LP GP)
(NOT (EQUAL (NTH GP K) 3)))
(EQUAL (NTH GP K) 4)).
Give the above formula the name *1.
Case 3. (IMPLIES (AND (MEMBER K (NSET N))
(EQUAL (NTH LP K) 10)
(LG N LP GP)
(NOT (EQUAL (NTH GP K) 3)))
(EQUAL (NTH GP K) 4)),
which we would usually push and work on later by induction. But if we must
use induction to prove the input conjecture, we prefer to induct on the
original formulation of the problem. Thus we will disregard all that we
have previously done, give the name *1 to the original input, and work on it.
So now let us consider:
(IMPLIES (AND (MEMBER K (NSET N))
(UNION-AT-N LP K '(9 10 11 12))
(LG N LP GP))
(UNION-AT-N GP K '(3 4))),
which we named *1 above. We will appeal to induction. There are two
plausible inductions. However, they merge into one likely candidate induction.
We will induct according to the following scheme:
(AND (IMPLIES (ZEROP N) (p GP K N LP))
(IMPLIES (AND (NOT (ZEROP N))
(p GP K (SUB1 N) LP))
(p GP K N LP))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP
establish that the measure (COUNT N) decreases according to the well-founded
relation LESSP in each induction step of the scheme. The above induction
scheme leads to the following three new goals:
Case 3. (IMPLIES (AND (ZEROP N)
(MEMBER K (NSET N))
(UNION-AT-N LP K '(9 10 11 12))
(LG N LP GP))
(UNION-AT-N GP K '(3 4))).
This simplifies, expanding the functions ZEROP, NSET, LISTP, and MEMBER, to:
T.
Case 2. (IMPLIES (AND (NOT (ZEROP N))
(NOT (MEMBER K (NSET (SUB1 N))))
(MEMBER K (NSET N))
(UNION-AT-N LP K '(9 10 11 12))
(LG N LP GP))
(UNION-AT-N GP K '(3 4))).
This simplifies, appealing to the lemmas CDR-CONS and CAR-CONS, and opening
up the definitions of ZEROP, NSET, MEMBER, LISTP, CAR, CDR, and UNION-AT-N,
to the following four new conjectures:
Case 2.4.
(IMPLIES (AND (NOT (EQUAL N 0))
(NUMBERP N)
(NOT (MEMBER K (NSET (SUB1 N))))
(EQUAL K N)
(EQUAL (NTH LP K) 9)
(LG K LP GP)
(NOT (EQUAL (NTH GP K) 3)))
(EQUAL (NTH GP K) 4)).
But this again simplifies, unfolding LG, LG-3-AT-N, EQUAL, AT, and LG-AT-N,
to:
T.
Case 2.3.
(IMPLIES (AND (NOT (EQUAL N 0))
(NUMBERP N)
(NOT (MEMBER K (NSET (SUB1 N))))
(EQUAL K N)
(EQUAL (NTH LP K) 10)
(LG K LP GP)
(NOT (EQUAL (NTH GP K) 3)))

which again simplifies, unfolding the definitions of LG, LG-3-AT-N, EQUAL,

to:
T.

definitions of ZEROP, NSET, MEMBER, LISTP, CAR, CDR, UNION-AT-N, LG,

Give the conjecture the name *1.
Let us appeal to the induction principle. The recursive terms in the
conjecture suggest three inductions. However, they merge into one likely
candidate induction. We will induct according to the following scheme:
(AND (IMPLIES (ZEROP N) (p N L G H J))
(IMPLIES (AND (NOT (ZEROP N))
(HINT-8-12-3-4-AT-N N L G H J))
(p N L G H J))
(IMPLIES (AND (NOT (ZEROP N))
(NOT (HINT-8-12-3-4-AT-N N L G H J))
(p (SUB1 N) L G H J))
(p N L G H J))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP can be
used to show that the measure (COUNT N) decreases according to the
well-founded relation LESSP in each induction step of the scheme. The above
induction scheme generates the following four new conjectures:
Case 4. (IMPLIES (AND (ZEROP N)
(EXIST-HINT-8-12-3-4 N L G H J))
(MEMBER (EXIST-HINT-8-12-3-4 N L G H J)
(NSET N))).
This simplifies, opening up the functions ZEROP, EQUAL, and
EXIST-HINT-8-12-3-4, to:
T.
Case 3. (IMPLIES (AND (NOT (ZEROP N))
(HINT-8-12-3-4-AT-N N L G H J)
(EXIST-HINT-8-12-3-4 N L G H J))
(MEMBER (EXIST-HINT-8-12-3-4 N L G H J)
(NSET N))).
This simplifies, rewriting with CAR-CONS, and opening up the definitions of
ZEROP, HINT-8-12-3-4-AT-N, EXIST-HINT-8-12-3-4, NSET, and MEMBER, to:
T.
Case 2. (IMPLIES (AND (NOT (ZEROP N))
(NOT (HINT-8-12-3-4-AT-N N L G H J))
(NOT (EXIST-HINT-8-12-3-4 (SUB1 N)
L G H J))
(EXIST-HINT-8-12-3-4 N L G H J))
(MEMBER (EXIST-HINT-8-12-3-4 N L G H J)
(NSET N))),
which simplifies, unfolding the functions ZEROP, HINT-8-12-3-4-AT-N, and
EXIST-HINT-8-12-3-4, to:
T.
Case 1. (IMPLIES (AND (NOT (ZEROP N))
(NOT (HINT-8-12-3-4-AT-N N L G H J))
(MEMBER (EXIST-HINT-8-12-3-4 (SUB1 N) L G H J)

functions ZEROP, HINT-8-12-3-4-AT-N, EXIST-HINT-8-12-3-4, NSET, and MEMBER,
to:

Name the conjecture *1.
We will appeal to induction. The recursive terms in the conjecture
suggest three inductions. However, they merge into one likely candidate
induction. We will induct according to the following scheme:
(AND (IMPLIES (OR (EQUAL J 0) (NOT (NUMBERP J)))
(p J N))
(IMPLIES (AND (NOT (OR (EQUAL J 0) (NOT (NUMBERP J))))
(OR (EQUAL N 0) (NOT (NUMBERP N))))

(IMPLIES (AND (NOT (OR (EQUAL J 0) (NOT (NUMBERP J))))
(NOT (OR (EQUAL N 0) (NOT (NUMBERP N))))
(p (SUB1 J) (SUB1 N)))
(p J N))).
Linear arithmetic, the lemmas SUB1-LESSEQP and SUB1-LESSP, and the definitions
of OR and NOT inform us that the measure (COUNT N) decreases according to the
well-founded relation LESSP in each induction step of the scheme. Note,
however, the inductive instance chosen for J. The above induction scheme
produces the following four new formulas:
Case 4. (IMPLIES (AND (OR (EQUAL J 0) (NOT (NUMBERP J)))
(LESSP N J))
(NOT (MEMBER J (NSET N)))).
This simplifies, applying NSET-NUMBER, and expanding NOT, OR, EQUAL, and
LESSP, to:
T.
Case 3. (IMPLIES (AND (NOT (OR (EQUAL J 0) (NOT (NUMBERP J))))
(OR (EQUAL N 0) (NOT (NUMBERP N)))
(LESSP N J))
(NOT (MEMBER J (NSET N)))),
which simplifies, applying NSET-NUMBER, and expanding the functions NOT, OR,
EQUAL, LESSP, NSET, LISTP, and MEMBER, to:
T.
Case 2. (IMPLIES (AND (NOT (OR (EQUAL J 0) (NOT (NUMBERP J))))
(NOT (OR (EQUAL N 0) (NOT (NUMBERP N))))
(NOT (LESSP (SUB1 N) (SUB1 J)))
(LESSP N J))
(NOT (MEMBER J (NSET N)))).
This simplifies, using linear arithmetic, to:
(IMPLIES (AND (LESSP N 1)
(NOT (OR (EQUAL J 0) (NOT (NUMBERP J))))
(NOT (OR (EQUAL N 0) (NOT (NUMBERP N))))
(NOT (LESSP (SUB1 N) (SUB1 J)))
(LESSP N J))
(NOT (MEMBER J (NSET N)))),
which again simplifies, applying the lemma NSET-NUMBER, and opening up SUB1,
NUMBERP, EQUAL, LESSP, NOT, and OR, to:
T.
Case 1. (IMPLIES (AND (NOT (OR (EQUAL J 0) (NOT (NUMBERP J))))
(NOT (OR (EQUAL N 0) (NOT (NUMBERP N))))
(NOT (MEMBER (SUB1 J) (NSET (SUB1 N))))
(LESSP N J))
(NOT (MEMBER J (NSET N)))),
which simplifies, rewriting with NSET-NUMBER, CDR-CONS, and CAR-CONS, and
opening up NOT, OR, LESSP, NSET, and MEMBER, to the following two new
formulas:
Case 1.2.
(IMPLIES (AND (NOT (EQUAL J 0))
(NOT (EQUAL N 0))
(NUMBERP N)
(NOT (MEMBER (SUB1 J) (NSET (SUB1 N))))
(LESSP (SUB1 N) (SUB1 J)))
(NOT (EQUAL J N))).
This again simplifies, using linear arithmetic, to:
T.
Case 1.1.
(IMPLIES (AND (NOT (EQUAL J 0))
(NOT (EQUAL N 0))
(NUMBERP N)
(NOT (MEMBER (SUB1 J) (NSET (SUB1 N))))
(LESSP (SUB1 N) (SUB1 J)))
(NOT (MEMBER J (NSET (SUB1 N))))),
which again simplifies, using linear arithmetic and applying ADD1-SUB1,
NSET-NUMBER, and ADD1-NSET, to the new goal:
(IMPLIES (AND (NOT (EQUAL J 0))
(NOT (EQUAL N 0))
(NUMBERP N)
(LESSP J 1)
(NOT (MEMBER (SUB1 J) (NSET (SUB1 N))))
(LESSP (SUB1 N) (SUB1 J)))
(NOT (MEMBER J (NSET (SUB1 N))))),
which again simplifies, using linear arithmetic, to the conjecture:
(IMPLIES (AND (NOT (NUMBERP J))
(NOT (EQUAL J 0))
(NOT (EQUAL N 0))
(NUMBERP N)
(LESSP J 1)
(NOT (MEMBER (SUB1 J) (NSET (SUB1 N))))
(LESSP (SUB1 N) (SUB1 J)))

Name the conjecture *1.
Perhaps we can prove it by induction. There are three plausible
inductions. They merge into two likely candidate inductions, both of which
are unflawed. However, one of these is more likely than the other. We will
induct according to the following scheme:
(AND (IMPLIES (ZEROP N) (p H K N I))
(IMPLIES (AND (NOT (ZEROP N))
(p H K (SUB1 N) I))
(p H K N I))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP
establish that the measure (COUNT N) decreases according to the well-founded
relation LESSP in each induction step of the scheme. The above induction
scheme leads to the following three new formulas:
Case 3. (IMPLIES (AND (ZEROP N)
(NUMBERP I)
(ALL-UNION H N (NSET I))
(MEMBER K (NSET N)))
(NUMBERP (NTH H K))).
This simplifies, opening up the definitions of ZEROP, EQUAL, ALL-UNION, NSET,
LISTP, and MEMBER, to:
T.
Case 2. (IMPLIES (AND (NOT (ZEROP N))
(NOT (ALL-UNION H (SUB1 N) (NSET I)))
(NUMBERP I)
(ALL-UNION H N (NSET I))
(MEMBER K (NSET N)))
(NUMBERP (NTH H K))).
This simplifies, expanding ZEROP, ALL-UNION, and UNION-AT-N, to:
T.
Case 1. (IMPLIES (AND (NOT (ZEROP N))
(NOT (MEMBER K (NSET (SUB1 N))))
(NUMBERP I)
(ALL-UNION H N (NSET I))
(MEMBER K (NSET N)))
(NUMBERP (NTH H K))).
This simplifies, rewriting with CDR-CONS and CAR-CONS, and unfolding the
definitions of ZEROP, ALL-UNION, UNION-AT-N, NSET, and MEMBER, to the goal:
(IMPLIES (AND (NOT (EQUAL N 0))
(NUMBERP N)
(NOT (MEMBER K (NSET (SUB1 N))))
(NUMBERP I)
(MEMBER (NTH H N) (NSET I))
(ALL-UNION H (SUB1 N) (NSET I))
(EQUAL K N))
(NUMBERP (NTH H K))).
But this again simplifies, using linear arithmetic and appealing to the

We will appeal to induction. There are two plausible inductions.
However, they merge into one likely candidate induction. We will induct
according to the following scheme:
(AND (IMPLIES (ZEROP N) (p N L K G))
(IMPLIES (AND (NOT (ZEROP N))
(p (SUB1 N) L K G))
(p N L K G))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP
establish that the measure (COUNT N) decreases according to the well-founded
relation LESSP in each induction step of the scheme. The above induction
scheme leads to the following three new conjectures:
Case 3. (IMPLIES (AND (ZEROP N)

We will appeal to induction. There are two plausible inductions.
However, they merge into one likely candidate induction. We will induct
according to the following scheme:
(AND (IMPLIES (ZEROP N) (p N L K G))
(IMPLIES (AND (NOT (ZEROP N))
(p (SUB1 N) L K G))
(p N L K G))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP
establish that the measure (COUNT N) decreases according to the well-founded
relation LESSP in each induction step of the scheme. The above induction
scheme leads to the following three new conjectures:
Case 3. (IMPLIES (AND (ZEROP N)
(LISTP L)
(LISTP G)
(MEMBER K (NSET (LENGTH L)))
(NUMBERP N)
(EQUAL (NTH L K) 3)

(LISTP G)

This simplifies, opening up the functions ZEROP and LG, to:

We will appeal to induction. There are two plausible inductions.
However, they merge into one likely candidate induction. We will induct
according to the following scheme:
(AND (IMPLIES (ZEROP N) (p N L K G))
(IMPLIES (AND (NOT (ZEROP N))
(p (SUB1 N) L K G))
(p N L K G))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP
establish that the measure (COUNT N) decreases according to the well-founded
relation LESSP in each induction step of the scheme. The above induction
scheme leads to the following three new conjectures:
Case 3. (IMPLIES (AND (ZEROP N)

We will appeal to induction. There are two plausible inductions.
However, they merge into one likely candidate induction. We will induct
according to the following scheme:
(AND (IMPLIES (ZEROP N) (p N L K G))
(IMPLIES (AND (NOT (ZEROP N))
(p (SUB1 N) L K G))
(p N L K G))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP
establish that the measure (COUNT N) decreases according to the well-founded
relation LESSP in each induction step of the scheme. The above induction
scheme leads to the following three new conjectures:

We will appeal to induction. Two inductions are suggested by terms in
the conjecture. However, they merge into one likely candidate induction. We
will induct according to the following scheme:
(AND (IMPLIES (ZEROP N) (p N L K G))
(IMPLIES (AND (NOT (ZEROP N))
(p (SUB1 N) L K G))
(p N L K G))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP can be
used to show that the measure (COUNT N) decreases according to the
well-founded relation LESSP in each induction step of the scheme. The above
induction scheme produces three new goals:
Case 3. (IMPLIES (AND (ZEROP N)
(LISTP L)
(LISTP G)
(MEMBER K (NSET (LENGTH L)))
(NUMBERP N)
(EQUAL (NTH L K) 12)

(LG N (MOVE L K 0) (MOVE G K 0))),
which simplifies, expanding the functions ZEROP and LG, to:
T.
Case 1. (IMPLIES (AND (NOT (ZEROP N))
(LG (SUB1 N)
(MOVE L K 0)
(MOVE G K 0))

Give the above formula the name *1.
Perhaps we can prove it by induction. There are two plausible inductions.
However, they merge into one likely candidate induction. We will induct
according to the following scheme:
(AND (IMPLIES (ZEROP N) (p L J G N))
(IMPLIES (AND (NOT (ZEROP N))

(p L J G N))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP can be
used to establish that the measure (COUNT N) decreases according to the
well-founded relation LESSP in each induction step of the scheme. The above
induction scheme generates three new formulas:
Case 3. (IMPLIES (AND (ZEROP N)

(EQUAL J N)
(EQUAL J 0)

(MRHOI N K L G H LP GP HP).
WARNING: Note that the proposed lemma COND-L5 is to be stored as zero type
prescription rules, zero compound recognizer rules, one linear rule, and zero
replacement rules.
This conjecture can be simplified, using the abbreviations AND, IMPLIES, and
AT, to the formula:
(IMPLIES (AND (MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER J (NSET N))
(MRHOI N K L G H LP GP HP)
(EQUAL (NTH L K) 5)
(LESSP J (NTH HP K)))
(LESSP (SUB1 J) (NTH H K))).
This simplifies, rewriting with SUB1-ADD1, MOLWS-NUM-K, MOLWS-N-NOT-0,
MOLWS-NUM-N, N-IN-NSET, and NTH-NUMBERP, and expanding MRHOI12, MRHOI11B,
MRHOI11A, MRHOI10, MRHOI9B, MRHOI9A, MRHOI8, MRHOI7B, MRHOI7A, MRHOI6, MRHOI5C,
MRHOI5B, LESSP, MRHOI5A, MRHOI4, MRHOI3B, MRHOI3A, MRHOI2, MRHOI1B, MRHOI1A,
MRHOI0, EQUAL, AT, MRHOI, and SUB1, to four new goals:
Case 4. (IMPLIES (AND (MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER J (NSET N))
(EQUAL GP G)
(EQUAL LP L)
(EQUAL (NTH H K) 0)
(NOT (EQUAL (NTH G (NTH H K)) 1))
(EQUAL HP (MOVE H K (ADD1 (NTH H K))))
(EQUAL (NTH L K) 5))
(NOT (LESSP J (NTH HP K)))),
which again simplifies, rewriting with the lemmas MOLWS-LN-H, MOLWS-LIST-H,
and MOVE-NTH, to:
(IMPLIES (AND (MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER J (NSET N))
(EQUAL (NTH H K) 0)
(NOT (EQUAL (NTH G 0) 1))
(EQUAL (NTH L K) 5))
(NOT (LESSP J 1))).
Name the above subgoal *1.
Case 3. (IMPLIES (AND (MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER J (NSET N))
(EQUAL GP G)
(EQUAL LP L)
(LESSP (SUB1 (NTH H K)) N)
(NOT (EQUAL (NTH G (NTH H K)) 1))
(EQUAL HP (MOVE H K (ADD1 (NTH H K))))
(EQUAL (NTH L K) 5)
(LESSP J (NTH HP K)))
(LESSP (SUB1 J) (NTH H K))).
But this again simplifies, applying MOLWS-LN-H, MOLWS-LIST-H, MOVE-NTH,
SUB1-ADD1, NTH-NUMBERP, and MOLWS-NUM-K, and expanding LESSP, SUB1, and
EQUAL, to:
(IMPLIES (AND (MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER J (NSET N))
(LESSP (SUB1 (NTH H K)) N)
(NOT (EQUAL (NTH G (NTH H K)) 1))
(EQUAL (NTH L K) 5)
(EQUAL J 0))
(NOT (EQUAL (NTH H K) 0))),
which again simplifies, rewriting with ZERO-NOT-MEMBER-NSET, to:
T.
Case 2. (IMPLIES (AND (MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER J (NSET N))
(EQUAL GP G)
(EQUAL HP H)
(LESSP (SUB1 (NTH H K)) N)
(EQUAL (NTH G (NTH H K)) 1)
(EQUAL LP (MOVE L K 6))
(EQUAL (NTH L K) 5)
(LESSP J (NTH H K)))
(LESSP (SUB1 J) (NTH H K))).
But this again simplifies, using linear arithmetic, to the formula:
(IMPLIES (AND (LESSP J 1)
(MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER J (NSET N))
(LESSP (SUB1 (NTH H K)) N)
(EQUAL (NTH G (NTH H K)) 1)
(EQUAL (NTH L K) 5)
(LESSP J (NTH H K)))
(LESSP (SUB1 J) (NTH H K))).
Appealing to the lemma SUB1-ELIM, we now replace J by (ADD1 X) to eliminate
(SUB1 J). We use the type restriction lemma noted when SUB1 was introduced
to constrain the new variable. This generates three new goals:
Case 2.3.
(IMPLIES (AND (EQUAL J 0)
(LESSP J 1)
(MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER J (NSET N))
(LESSP (SUB1 (NTH H K)) N)
(EQUAL (NTH G (NTH H K)) 1)
(EQUAL (NTH L K) 5)
(LESSP J (NTH H K)))
(LESSP (SUB1 J) (NTH H K))),
which further simplifies, rewriting with ZERO-NOT-MEMBER-NSET, and opening
up the function LESSP, to:
T.
Case 2.2.
(IMPLIES (AND (NOT (NUMBERP J))
(LESSP J 1)
(MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER J (NSET N))
(LESSP (SUB1 (NTH H K)) N)
(EQUAL (NTH G (NTH H K)) 1)
(EQUAL (NTH L K) 5)
(LESSP J (NTH H K)))
(LESSP (SUB1 J) (NTH H K))).
But this further simplifies, rewriting with MOLWS-NUM-K, to:
T.
Case 2.1.
(IMPLIES (AND (NUMBERP X)
(NOT (EQUAL (ADD1 X) 0))
(LESSP (ADD1 X) 1)
(MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER (ADD1 X) (NSET N))
(LESSP (SUB1 (NTH H K)) N)
(EQUAL (NTH G (NTH H K)) 1)
(EQUAL (NTH L K) 5)
(LESSP (ADD1 X) (NTH H K)))
(LESSP X (NTH H K))).
However this further simplifies, using linear arithmetic, to:
T.
Case 1. (IMPLIES (AND (MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER J (NSET N))
(EQUAL GP G)
(EQUAL HP H)
(EQUAL (NTH H K) (ADD1 N))
(EQUAL LP (MOVE L K 8))
(EQUAL (NTH L K) 5)
(LESSP (SUB1 J) N)
(NOT (EQUAL (SUB1 J) 0)))
(LESSP (SUB1 (SUB1 J)) N)),
which again simplifies, using linear arithmetic, to:
(IMPLIES (AND (LESSP J 1)
(MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER J (NSET N))
(EQUAL (NTH H K) (ADD1 N))
(EQUAL (NTH L K) 5)
(LESSP (SUB1 J) N)
(NOT (EQUAL (SUB1 J) 0)))
(LESSP (SUB1 (SUB1 J)) N)).
Appealing to the lemma SUB1-ELIM, we now replace J by (ADD1 X) to eliminate
(SUB1 J) and X by (ADD1 Z) to eliminate (SUB1 X). We rely upon the type
restriction lemma noted when SUB1 was introduced to constrain the new
variable. This generates three new goals:
Case 1.3.
(IMPLIES (AND (EQUAL J 0)
(LESSP J 1)
(MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER J (NSET N))
(EQUAL (NTH H K) (ADD1 N))
(EQUAL (NTH L K) 5)
(LESSP (SUB1 J) N)
(NOT (EQUAL (SUB1 J) 0)))
(LESSP (SUB1 (SUB1 J)) N)),
which further simplifies, rewriting with ZERO-NOT-MEMBER-NSET, and opening
up the function LESSP, to:
T.
Case 1.2.
(IMPLIES (AND (NOT (NUMBERP J))
(LESSP J 1)
(MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER J (NSET N))
(EQUAL (NTH H K) (ADD1 N))
(EQUAL (NTH L K) 5)
(LESSP (SUB1 J) N)
(NOT (EQUAL (SUB1 J) 0)))
(LESSP (SUB1 (SUB1 J)) N)).
However this further simplifies, rewriting with the lemma MOLWS-NUM-K, to:
T.
Case 1.1.
(IMPLIES (AND (NUMBERP Z)
(NOT (EQUAL (ADD1 (ADD1 Z)) 0))
(LESSP (ADD1 (ADD1 Z)) 1)
(MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER (ADD1 (ADD1 Z)) (NSET N))
(EQUAL (NTH H K) (ADD1 N))
(EQUAL (NTH L K) 5)
(LESSP (ADD1 Z) N)
(NOT (EQUAL (ADD1 Z) 0)))
(LESSP Z N)),
which further simplifies, using linear arithmetic, to:
T.
So next consider:
(IMPLIES (AND (MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER J (NSET N))
(EQUAL (NTH H K) 0)
(NOT (EQUAL (NTH G 0) 1))
(EQUAL (NTH L K) 5))
(NOT (LESSP J 1))),
named *1 above. We will try to prove it by induction. There is only one
suggested induction. We will induct according to the following scheme:
(AND (IMPLIES (OR (EQUAL 1 0) (NOT (NUMBERP 1)))
(p J L K G H N))
(IMPLIES (AND (NOT (OR (EQUAL 1 0) (NOT (NUMBERP 1))))
(OR (EQUAL J 0) (NOT (NUMBERP J))))
(p J L K G H N))
(IMPLIES (AND (NOT (OR (EQUAL 1 0) (NOT (NUMBERP 1))))
(NOT (OR (EQUAL J 0) (NOT (NUMBERP J))))
(p (SUB1 J) L K G H N))
(p J L K G H N))).
Linear arithmetic, the lemmas SUB1-LESSEQP and SUB1-LESSP, and the definitions
of OR and NOT establish that the measure (COUNT J) decreases according to the
well-founded relation LESSP in each induction step of the scheme. The above
induction scheme generates four new goals:
Case 4. (IMPLIES (AND (OR (EQUAL 1 0) (NOT (NUMBERP 1)))
(MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER J (NSET N))
(EQUAL (NTH H K) 0)
(NOT (EQUAL (NTH G 0) 1))
(EQUAL (NTH L K) 5))
(NOT (LESSP J 1))),
which simplifies, expanding the functions EQUAL, NUMBERP, NOT, and OR, to:
T.
Case 3. (IMPLIES (AND (NOT (OR (EQUAL 1 0) (NOT (NUMBERP 1))))
(OR (EQUAL J 0) (NOT (NUMBERP J)))
(MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER J (NSET N))
(EQUAL (NTH H K) 0)
(NOT (EQUAL (NTH G 0) 1))
(EQUAL (NTH L K) 5))
(NOT (LESSP J 1))),
which simplifies, rewriting with MOLWS-NUM-K and ZERO-NOT-MEMBER-NSET, and
opening up EQUAL, NUMBERP, NOT, and OR, to:
T.
Case 2. (IMPLIES (AND (NOT (OR (EQUAL 1 0) (NOT (NUMBERP 1))))
(NOT (OR (EQUAL J 0) (NOT (NUMBERP J))))
(NOT (MEMBER (SUB1 J) (NSET N)))
(MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER J (NSET N))
(EQUAL (NTH H K) 0)
(NOT (EQUAL (NTH G 0) 1))
(EQUAL (NTH L K) 5))
(NOT (LESSP J 1))).
This simplifies, appealing to the lemma MOLWS-NUM-K, and expanding EQUAL,
NUMBERP, NOT, OR, LESSP, and SUB1, to:
T.
Case 1. (IMPLIES (AND (NOT (OR (EQUAL 1 0) (NOT (NUMBERP 1))))
(NOT (OR (EQUAL J 0) (NOT (NUMBERP J))))
(NOT (LESSP (SUB1 J) 1))
(MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER J (NSET N))
(EQUAL (NTH H K) 0)
(NOT (EQUAL (NTH G 0) 1))
(EQUAL (NTH L K) 5))
(NOT (LESSP J 1))).
This simplifies, rewriting with MOLWS-NUM-K, and unfolding the functions
EQUAL, NUMBERP, NOT, OR, LESSP, and SUB1, to:

So let us turn our attention to:
(IMPLIES (AND (MOLWS N L G H)
(MEMBER J (NSET N))
(MEMBER K (NSET N))
(EQUAL (NTH L K) 4))
(NOT (LESSP J 1))),
which we named *1 above. We will try to prove it by induction. There is only
one suggested induction. We will induct according to the following scheme:
(AND (IMPLIES (OR (EQUAL 1 0) (NOT (NUMBERP 1)))
(p J L K N G H))
(IMPLIES (AND (NOT (OR (EQUAL 1 0) (NOT (NUMBERP 1))))
(OR (EQUAL J 0) (NOT (NUMBERP J))))
(p J L K N G H))

(NOT (OR (EQUAL J 0) (NOT (NUMBERP J))))
(p (SUB1 J) L K N G H))
(p J L K N G H))).
Linear arithmetic, the lemmas SUB1-LESSEQP and SUB1-LESSP, and the definitions
of OR and NOT can be used to prove that the measure (COUNT J) decreases
according to the well-founded relation LESSP in each induction step of the
scheme. The above induction scheme generates the following four new goals:
Case 4. (IMPLIES (AND (OR (EQUAL 1 0) (NOT (NUMBERP 1)))
(MOLWS N L G H)
(MEMBER J (NSET N))
(MEMBER K (NSET N))
(EQUAL (NTH L K) 4))
(NOT (LESSP J 1))).
This simplifies, opening up the functions EQUAL, NUMBERP, NOT, and OR, to:
T.
Case 3. (IMPLIES (AND (NOT (OR (EQUAL 1 0) (NOT (NUMBERP 1))))
(OR (EQUAL J 0) (NOT (NUMBERP J)))
(MOLWS N L G H)
(MEMBER J (NSET N))
(MEMBER K (NSET N))
(EQUAL (NTH L K) 4))
(NOT (LESSP J 1))).
This simplifies, applying the lemmas MOLWS-NUM-K and ZERO-NOT-MEMBER-NSET,
and unfolding EQUAL, NUMBERP, NOT, and OR, to:
T.
Case 2. (IMPLIES (AND (NOT (OR (EQUAL 1 0) (NOT (NUMBERP 1))))
(NOT (OR (EQUAL J 0) (NOT (NUMBERP J))))
(NOT (MEMBER (SUB1 J) (NSET N)))
(MOLWS N L G H)
(MEMBER J (NSET N))
(MEMBER K (NSET N))
(EQUAL (NTH L K) 4))
(NOT (LESSP J 1))).
This simplifies, applying the lemma MOLWS-NUM-K, and unfolding the
definitions of EQUAL, NUMBERP, NOT, OR, LESSP, and SUB1, to:
T.
Case 1. (IMPLIES (AND (NOT (OR (EQUAL 1 0) (NOT (NUMBERP 1))))

WARNING: Note that B0B-IF1 contains the free variables L and N which will be

This conjecture can be simplified, using the abbreviations AND, IMPLIES, and
AT, to the formula:
(IMPLIES (AND (MEMBER J (NSET N))
(LG N L G)
(EQUAL (NTH L J) 3))
(EQUAL (NTH G J) 1)).
Name the above subgoal *1.
We will appeal to induction. Two inductions are suggested by terms in
the conjecture. However, they merge into one likely candidate induction. We
will induct according to the following scheme:
(AND (IMPLIES (ZEROP N) (p G J L N))
(IMPLIES (AND (NOT (ZEROP N))
(p G J L (SUB1 N)))
(p G J L N))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP inform
us that the measure (COUNT N) decreases according to the well-founded relation
LESSP in each induction step of the scheme. The above induction scheme leads
to the following three new goals:
Case 3. (IMPLIES (AND (ZEROP N)
(MEMBER J (NSET N))
(LG N L G)
(EQUAL (NTH L J) 3))
(EQUAL (NTH G J) 1)).
This simplifies, opening up the functions ZEROP, NSET, LISTP, and MEMBER, to:
T.
Case 2. (IMPLIES (AND (NOT (ZEROP N))
(NOT (MEMBER J (NSET (SUB1 N))))
(MEMBER J (NSET N))
(LG N L G)
(EQUAL (NTH L J) 3))
(EQUAL (NTH G J) 1)).
This simplifies, rewriting with CDR-CONS and CAR-CONS, and unfolding the
definitions of ZEROP, NSET, MEMBER, LG-AT-N, AT, EQUAL, LG-1-AT-N, and LG,
to:
(IMPLIES (AND (NOT (EQUAL N 0))
(NUMBERP N)
(NOT (MEMBER J (NSET (SUB1 N))))
(EQUAL J N)
(EQUAL J 0)
(EQUAL (NTH L 0) 3))
(EQUAL (NTH G 0) 1)).
This again simplifies, obviously, to:
T.
Case 1. (IMPLIES (AND (NOT (ZEROP N))
(NOT (LG (SUB1 N) L G))
(MEMBER J (NSET N))
(LG N L G)
(EQUAL (NTH L J) 3))
(EQUAL (NTH G J) 1)).
This simplifies, applying CDR-CONS and CAR-CONS, and opening up ZEROP, NSET,
MEMBER, LG-AT-N, AT, EQUAL, LG-1-AT-N, and LG, to:
(IMPLIES (AND (NOT (EQUAL N 0))
(NUMBERP N)
(NOT (LG (SUB1 N) L G))
(EQUAL J N)
(EQUAL J 0)
(EQUAL (NTH L 0) 3))
(EQUAL (NTH G 0) 1)).
This again simplifies, trivially, to:

which simplifies, expanding the functions CDR, CAR, LISTP, and MEMBER, to
three new formulas:
Case 3. (IMPLIES (AND (MEMBER I (NSET N))
(LG N L G)
(EQUAL (NTH L I) 5))
(NOT (EQUAL (NTH G I) 0))),
which we will name *1.
Case 2. (IMPLIES (AND (MEMBER I (NSET N))
(LG N L G)
(EQUAL (NTH L I) 5))
(NOT (EQUAL (NTH G I) 1))),
which we would usually push and work on later by induction. But if we must
use induction to prove the input conjecture, we prefer to induct on the
original formulation of the problem. Thus we will disregard all that we
have previously done, give the name *1 to the original input, and work on it.

We gave this the name *1 above. Perhaps we can prove it by induction. Two
inductions are suggested by terms in the conjecture. However, they merge into
one likely candidate induction. We will induct according to the following
scheme:
(AND (IMPLIES (ZEROP N) (p G I L N))
(IMPLIES (AND (NOT (ZEROP N))
(p G I L (SUB1 N)))
(p G I L N))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP can be
used to establish that the measure (COUNT N) decreases according to the
well-founded relation LESSP in each induction step of the scheme. The above
induction scheme produces three new goals:
Case 3. (IMPLIES (AND (ZEROP N)
(MEMBER I (NSET N))
(LG N L G)
(AT L I 5))
(NOT (UNION-AT-N G I '(0 1 2)))),
which simplifies, opening up the definitions of ZEROP, NSET, LISTP, and
MEMBER, to:
T.
Case 2. (IMPLIES (AND (NOT (ZEROP N))
(NOT (MEMBER I (NSET (SUB1 N))))
(MEMBER I (NSET N))
(LG N L G)
(AT L I 5))
(NOT (UNION-AT-N G I '(0 1 2)))),
which simplifies, applying CDR-CONS and CAR-CONS, and unfolding ZEROP, NSET,
MEMBER, AT, LISTP, CAR, CDR, and UNION-AT-N, to the following three new
conjectures:
Case 2.3.
(IMPLIES (AND (NOT (EQUAL N 0))
(NUMBERP N)
(NOT (MEMBER I (NSET (SUB1 N))))
(EQUAL I N)
(LG I L G)
(EQUAL (NTH L I) 5))
(NOT (EQUAL (NTH G I) 0))).
However this again simplifies, using linear arithmetic, applying
N-NOT-LESS-J, and expanding LG, LG-2-AT-N, EQUAL, AT, and LG-AT-N, to:
T.
Case 2.2.
(IMPLIES (AND (NOT (EQUAL N 0))
(NUMBERP N)
(NOT (MEMBER I (NSET (SUB1 N))))
(EQUAL I N)
(LG I L G)
(EQUAL (NTH L I) 5))
(NOT (EQUAL (NTH G I) 1))).
But this again simplifies, using linear arithmetic, rewriting with
N-NOT-LESS-J, and unfolding the definitions of LG, LG-2-AT-N, EQUAL, AT,
and LG-AT-N, to:
T.
Case 2.1.
(IMPLIES (AND (NOT (EQUAL N 0))
(NUMBERP N)
(NOT (MEMBER I (NSET (SUB1 N))))
(EQUAL I N)
(LG I L G)
(EQUAL (NTH L I) 5))
(NOT (EQUAL (NTH G I) 2))).
This again simplifies, using linear arithmetic, rewriting with
N-NOT-LESS-J, and opening up the definitions of LG, LG-2-AT-N, EQUAL, AT,
and LG-AT-N, to:
T.
Case 1. (IMPLIES (AND (NOT (ZEROP N))
(NOT (LG (SUB1 N) L G))
(MEMBER I (NSET N))
(LG N L G)
(AT L I 5))
(NOT (UNION-AT-N G I '(0 1 2)))).
This simplifies, rewriting with CDR-CONS and CAR-CONS, and expanding the
functions ZEROP, NSET, MEMBER, AT, LISTP, CAR, CDR, UNION-AT-N, LG,
LG-2-AT-N, EQUAL, and LG-AT-N, to three new formulas:
Case 1.3.
(IMPLIES (AND (NOT (EQUAL N 0))
(NUMBERP N)
(NOT (LG (SUB1 N) L G))
(EQUAL I N)
(LG I L G)
(EQUAL (NTH L I) 5))
(NOT (EQUAL (NTH G I) 0))),
which again simplifies, expanding LG, LG-2-AT-N, EQUAL, AT, and LG-AT-N,
to:
T.
Case 1.2.
(IMPLIES (AND (NOT (EQUAL N 0))
(NUMBERP N)
(NOT (LG (SUB1 N) L G))
(EQUAL I N)
(LG I L G)
(EQUAL (NTH L I) 5))
(NOT (EQUAL (NTH G I) 1))),
which again simplifies, expanding the definitions of LG, LG-2-AT-N, EQUAL,
AT, and LG-AT-N, to:
T.
Case 1.1.
(IMPLIES (AND (NOT (EQUAL N 0))
(NUMBERP N)
(NOT (LG (SUB1 N) L G))
(EQUAL I N)
(LG I L G)
(EQUAL (NTH L I) 5))
(NOT (EQUAL (NTH G I) 2))),
which again simplifies, expanding LG, LG-2-AT-N, EQUAL, AT, and LG-AT-N,
to:
T.

(EQUAL (NTH L K) 3)
(LESSP (SUB1 I) N)
(NOT (EQUAL (SUB1 I) 0)))
(LESSP (SUB1 (SUB1 I)) N)).
Appealing to the lemma SUB1-ELIM, we now replace I by (ADD1 X) to eliminate
(SUB1 I) and X by (ADD1 Z) to eliminate (SUB1 X). We use the type
restriction lemma noted when SUB1 was introduced to constrain the new
variable. This generates three new goals:
Case 1.3.
(IMPLIES (AND (EQUAL I 0)
(LESSP I 1)
(MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER I (NSET N))
(EQUAL (NTH H K) (ADD1 N))
(EQUAL (NTH L K) 3)
(LESSP (SUB1 I) N)

(LESSP (SUB1 (SUB1 I)) N)),
which further simplifies, rewriting with ZERO-NOT-MEMBER-NSET, and opening
up the function LESSP, to:
T.
Case 1.2.
(IMPLIES (AND (NOT (NUMBERP I))
(LESSP I 1)
(MOLWS N L G H)

But this further simplifies, rewriting with MOLWS-NUM-K, to:
T.
Case 1.1.
(IMPLIES (AND (NUMBERP Z)
(NOT (EQUAL (ADD1 (ADD1 Z)) 0))
(LESSP (ADD1 (ADD1 Z)) 1)

(EQUAL (NTH H K) (ADD1 N))
(EQUAL (NTH L K) 3)
(LESSP (ADD1 Z) N)
(NOT (EQUAL (ADD1 Z) 0)))
(LESSP Z N)).
However this further simplifies, using linear arithmetic, to:
T.
So next consider:
(IMPLIES (AND (MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER I (NSET N))
(EQUAL (NTH H K) 0)
(UNION-AT-N G 0 '(0 1 2))
(EQUAL (NTH L K) 3))
(NOT (LESSP I 1))),
named *1 above. Let us appeal to the induction principle. There is only one
suggested induction. We will induct according to the following scheme:
(AND (IMPLIES (OR (EQUAL 1 0) (NOT (NUMBERP 1)))
(p I L K G H N))
(IMPLIES (AND (NOT (OR (EQUAL 1 0) (NOT (NUMBERP 1))))
(OR (EQUAL I 0) (NOT (NUMBERP I))))
(p I L K G H N))
(IMPLIES (AND (NOT (OR (EQUAL 1 0) (NOT (NUMBERP 1))))
(NOT (OR (EQUAL I 0) (NOT (NUMBERP I))))
(p (SUB1 I) L K G H N))
(p I L K G H N))).
Linear arithmetic, the lemmas SUB1-LESSEQP and SUB1-LESSP, and the definitions
of OR and NOT inform us that the measure (COUNT I) decreases according to the
well-founded relation LESSP in each induction step of the scheme. The above
induction scheme generates four new goals:
Case 4. (IMPLIES (AND (OR (EQUAL 1 0) (NOT (NUMBERP 1)))
(MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER I (NSET N))
(EQUAL (NTH H K) 0)
(UNION-AT-N G 0 '(0 1 2))
(EQUAL (NTH L K) 3))
(NOT (LESSP I 1))),
which simplifies, opening up the definitions of EQUAL, NUMBERP, NOT, and OR,
to:
T.
Case 3. (IMPLIES (AND (NOT (OR (EQUAL 1 0) (NOT (NUMBERP 1))))
(OR (EQUAL I 0) (NOT (NUMBERP I)))
(MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER I (NSET N))
(EQUAL (NTH H K) 0)
(UNION-AT-N G 0 '(0 1 2))
(EQUAL (NTH L K) 3))
(NOT (LESSP I 1))),
which simplifies, rewriting with the lemmas MOLWS-NUM-K and
ZERO-NOT-MEMBER-NSET, and unfolding the definitions of EQUAL, NUMBERP, NOT,
and OR, to:
T.
Case 2. (IMPLIES (AND (NOT (OR (EQUAL 1 0) (NOT (NUMBERP 1))))
(NOT (OR (EQUAL I 0) (NOT (NUMBERP I))))
(NOT (MEMBER (SUB1 I) (NSET N)))
(MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER I (NSET N))
(EQUAL (NTH H K) 0)
(UNION-AT-N G 0 '(0 1 2))
(EQUAL (NTH L K) 3))
(NOT (LESSP I 1))),
which simplifies, applying MOLWS-NUM-K, and opening up the functions EQUAL,
NUMBERP, NOT, OR, LESSP, and SUB1, to:
T.
Case 1. (IMPLIES (AND (NOT (OR (EQUAL 1 0) (NOT (NUMBERP 1))))
(NOT (OR (EQUAL I 0) (NOT (NUMBERP I))))
(NOT (LESSP (SUB1 I) 1))
(MOLWS N L G H)
(MEMBER K (NSET N))
(MEMBER I (NSET N))
(EQUAL (NTH H K) 0)
(UNION-AT-N G 0 '(0 1 2))
(EQUAL (NTH L K) 3))
(NOT (LESSP I 1))).
This simplifies, applying the lemma MOLWS-NUM-K, and expanding the functions
EQUAL, NUMBERP, NOT, OR, LESSP, and SUB1, to:
T.

Linear arithmetic, the lemmas SUB1-LESSEQP and SUB1-LESSP, and the definitions
of OR and NOT inform us that the measure (COUNT I) decreases according to the
well-founded relation LESSP in each induction step of the scheme. The above
induction scheme generates the following four new formulas:
Case 4. (IMPLIES (AND (OR (EQUAL 1 0) (NOT (NUMBERP 1)))
(MOLWS N L G H)
(MEMBER I (NSET N))
(MEMBER K (NSET N))
(EQUAL (NTH L K) 2))
(NOT (LESSP I 1))).
This simplifies, opening up EQUAL, NUMBERP, NOT, and OR, to:
T.
Case 3. (IMPLIES (AND (NOT (OR (EQUAL 1 0) (NOT (NUMBERP 1))))
(OR (EQUAL I 0) (NOT (NUMBERP I)))
(MOLWS N L G H)
(MEMBER I (NSET N))
(MEMBER K (NSET N))
(EQUAL (NTH L K) 2))
(NOT (LESSP I 1))).
This simplifies, rewriting with MOLWS-NUM-K and ZERO-NOT-MEMBER-NSET, and
opening up the functions EQUAL, NUMBERP, NOT, and OR, to:
T.
Case 2. (IMPLIES (AND (NOT (OR (EQUAL 1 0) (NOT (NUMBERP 1))))
(NOT (OR (EQUAL I 0) (NOT (NUMBERP I))))

(MOLWS N L G H)
(MEMBER I (NSET N))
(MEMBER K (NSET N))
(EQUAL (NTH L K) 2))
(NOT (LESSP I 1))),
which simplifies, rewriting with MOLWS-NUM-K, and opening up the definitions
of EQUAL, NUMBERP, NOT, OR, LESSP, and SUB1, to:
T.
Case 1. (IMPLIES (AND (NOT (OR (EQUAL 1 0) (NOT (NUMBERP 1))))

WARNING: When the linear lemma L5-J-LT-H-K is stored under (NTH H K) it
contains the free variables HP, GP, LP, J, G, L, and N which will be chosen by
instantiating the hypotheses (MOLWS N L G H), (MEMBER J (NSET N)), and:
(MRHOI N K L G H LP GP HP).
WARNING: Note that the proposed lemma L5-J-LT-H-K is to be stored as zero
type prescription rules, zero compound recognizer rules, one linear rule, and
zero replacement rules.
This formula can be simplified, using the abbreviations AND, IMPLIES,
UNION-AT-N, and AT, to:

WARNING: Note that L8-11-K-IN-GP34 contains the free variables G, L, and N
which will be chosen by instantiating the hypotheses (MEMBER R (NSET N)) and
(LG N L G).
This conjecture can be simplified, using the abbreviations AND, IMPLIES, and
UNION-AT-N, to the formula:
(IMPLIES (AND (MEMBER R (NSET N))
(LG N L G)
(MEMBER (NTH L R) '(8 9 10 11)))
(MEMBER (NTH GP R) '(3 4))).
This simplifies, expanding the functions CDR, CAR, LISTP, and MEMBER, to the
following four new formulas:
Case 4. (IMPLIES (AND (MEMBER R (NSET N))
(LG N L G)
(EQUAL (NTH L R) 8)
(NOT (EQUAL (NTH GP R) 3)))
(EQUAL (NTH GP R) 4)).
Give the above formula the name *1.
Case 3. (IMPLIES (AND (MEMBER R (NSET N))
(LG N L G)
(EQUAL (NTH L R) 9)
(NOT (EQUAL (NTH GP R) 3)))
(EQUAL (NTH GP R) 4)),
which we would usually push and work on later by induction. But if we must
use induction to prove the input conjecture, we prefer to induct on the
original formulation of the problem. Thus we will disregard all that we
have previously done, give the name *1 to the original input, and work on it.
So now let us consider:
(IMPLIES (AND (MEMBER R (NSET N))
(LG N L G)
(UNION-AT-N L R '(8 9 10 11)))
(UNION-AT-N GP R '(3 4))),
which we named *1 above. We will appeal to induction. There are two
plausible inductions. However, they merge into one likely candidate induction.
We will induct according to the following scheme:
(AND (IMPLIES (ZEROP N) (p GP R L N G))
(IMPLIES (AND (NOT (ZEROP N))
(p GP R L (SUB1 N) G))
(p GP R L N G))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP
establish that the measure (COUNT N) decreases according to the well-founded
relation LESSP in each induction step of the scheme. The above induction
scheme leads to the following three new goals:
Case 3. (IMPLIES (AND (ZEROP N)
(MEMBER R (NSET N))
(LG N L G)
(UNION-AT-N L R '(8 9 10 11)))
(UNION-AT-N GP R '(3 4))).
This simplifies, expanding the functions ZEROP, NSET, LISTP, and MEMBER, to:
T.
Case 2. (IMPLIES (AND (NOT (ZEROP N))
(NOT (MEMBER R (NSET (SUB1 N))))
(MEMBER R (NSET N))
(LG N L G)
(UNION-AT-N L R '(8 9 10 11)))
(UNION-AT-N GP R '(3 4))).
This simplifies, appealing to the lemmas CDR-CONS and CAR-CONS, and opening
up the definitions of ZEROP, NSET, MEMBER, LG, LG-3-AT-N, LG-2-AT-N, AT,
EQUAL, LG-AT-N, UNION-AT-N, LISTP, CAR, and CDR, to the following 15 new
conjectures:
Case 2.15.
(IMPLIES (AND (NOT (EQUAL N 0))
(NUMBERP N)
(NOT (MEMBER R (NSET (SUB1 N))))
(EQUAL R N)
(LG-1-AT-N N L G)

(EQUAL (NTH G N) 4)
(LG (SUB1 N) L G)
(NOT (EQUAL (NTH GP N) 3)))
(EQUAL (NTH GP N) 4)).
But this again simplifies, using linear arithmetic, to:
T.

Name the above subgoal *1.
We will appeal to induction. Two inductions are suggested by terms in
the conjecture. However, they merge into one likely candidate induction. We
will induct according to the following scheme:
(AND (IMPLIES (ZEROP N) (p L U G N))
(IMPLIES (AND (NOT (ZEROP N))
(p L U G (SUB1 N)))
(p L U G N))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP inform
us that the measure (COUNT N) decreases according to the well-founded relation
LESSP in each induction step of the scheme. The above induction scheme leads
to the following three new formulas:
Case 3. (IMPLIES (AND (ZEROP N)
(MEMBER U (NSET N))
(LG N L G)

(NOT (EQUAL (NTH L U) 2))).

which we will name *1.
Perhaps we can prove it by induction. There are six plausible inductions.
However, they merge into one likely candidate induction. We will induct
according to the following scheme:
(AND (IMPLIES (ZEROP N) (p L N G H J))
(IMPLIES (AND (NOT (ZEROP N))
(HINT-8-12-3-4-AT-N N L G H J))

(p L N G H J))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP inform
us that the measure (COUNT N) decreases according to the well-founded relation
LESSP in each induction step of the scheme. The above induction scheme
generates the following eight new goals:
Case 8. (IMPLIES (AND (ZEROP N)

Call the above conjecture *1.
Perhaps we can prove it by induction. There are three plausible
inductions. However, they merge into one likely candidate induction. We will
induct according to the following scheme:
(AND (IMPLIES (ZEROP N) (p G N L H K))
(IMPLIES (AND (NOT (ZEROP N))

Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP
establish that the measure (COUNT N) decreases according to the well-founded
relation LESSP in each induction step of the scheme. The above induction
scheme generates the following five new goals:

Give the conjecture the name *1.
Perhaps we can prove it by induction. The recursive terms in the
conjecture suggest two inductions. However, they merge into one likely
candidate induction. We will induct according to the following scheme:
(AND (IMPLIES (ZEROP N) (p N L G H J))
(IMPLIES (AND (NOT (ZEROP N))
(HINT-8-12-3-4-AT-N N L G H J))

(p (SUB1 N) L G H J))
(p N L G H J))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP
establish that the measure (COUNT N) decreases according to the well-founded
relation LESSP in each induction step of the scheme. The above induction
scheme leads to the following four new conjectures:

Call the conjecture *1.
Let us appeal to the induction principle. Two inductions are suggested
by terms in the conjecture. However, they merge into one likely candidate
induction. We will induct according to the following scheme:
(AND (IMPLIES (ZEROP N) (p N LP GP H J R))
(IMPLIES (AND (NOT (ZEROP N))

Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP
establish that the measure (COUNT N) decreases according to the well-founded

(EQUAL (NTH H K) (ADD1 (LENGTH L)))
(MEMBER K (NSET (LENGTH L)))
(LG (LENGTH L) L G)
(EQUAL (NTH L K) 5)
(NOT (EQUAL (NTH G K) 3)))
(EQUAL (NTH G K) 4)),
named *1 above. We will appeal to induction. The recursive terms in the
conjecture suggest three inductions. However, they merge into one likely
candidate induction. We will induct according to the following scheme:
(AND (IMPLIES (AND (LISTP L) (p G K (CDR L) H))
(p G K L H))
(IMPLIES (NOT (LISTP L))
(p G K L H))).
Linear arithmetic and the lemma CDR-LESSP inform us that the measure (COUNT L)
decreases according to the well-founded relation LESSP in each induction step
of the scheme. The above induction scheme produces the following five new
formulas:
Case 5. (IMPLIES (AND (NOT (LISTP (CDR L)))
(LISTP L)
(EQUAL (NTH H K) (ADD1 (LENGTH L)))
(MEMBER K (NSET (LENGTH L)))
(LG (LENGTH L) L G)
(EQUAL (NTH L K) 5)
(NOT (EQUAL (NTH G K) 3)))
(EQUAL (NTH G K) 4)).
This simplifies, rewriting with SUB1-ADD1, CDR-CONS, and CAR-CONS, and
expanding the functions LENGTH, NSET, MEMBER, LG-AT-N, AT, EQUAL, LG-2-AT-N,
LG, and LG-3-AT-N, to 21 new conjectures:

(EQUAL (NTH L J) 12)),
which we will name *1.
Perhaps we can prove it by induction. The recursive terms in the
conjecture suggest two inductions. However, they merge into one likely
candidate induction. We will induct according to the following scheme:
(AND (IMPLIES (ZEROP N) (p L J G N))
(IMPLIES (AND (NOT (ZEROP N))
(p L J G (SUB1 N)))
(p L J G N))).
Linear arithmetic, the lemma COUNT-NUMBERP, and the definition of ZEROP can be
used to establish that the measure (COUNT N) decreases according to the
well-founded relation LESSP in each induction step of the scheme. The above
induction scheme leads to three new goals:
Case 3. (IMPLIES (AND (ZEROP N)
(MEMBER J (NSET N))
(LG N L G)
(EQUAL (NTH G J) 4)
(NOT (EQUAL (NTH L J) 9))
(NOT (EQUAL (NTH L J) 10))
(NOT (EQUAL (NTH L J) 11)))
(EQUAL (NTH L J) 12)),
which simplifies, opening up the functions ZEROP, NSET, LISTP, and MEMBER,
to:
T.
Case 2. (IMPLIES (AND (NOT (ZEROP N))
(NOT (MEMBER J (NSET (SUB1 N))))
(MEMBER J (NSET N))
(LG N L G)
(EQUAL (NTH G J) 4)
(NOT (EQUAL (NTH L J) 9))
(NOT (EQUAL (NTH L J) 10))
(NOT (EQUAL (NTH L J) 11)))
(EQUAL (NTH L J) 12)),
which simplifies, appealing to the lemmas CDR-CONS and CAR-CONS, and
unfolding the definitions of ZEROP, NSET, MEMBER, LG-AT-N, AT, LG-3-AT-N,
and LG, to:
(IMPLIES (AND (NOT (EQUAL N 0))
(NUMBERP N)
(NOT (MEMBER J (NSET (SUB1 N))))
(EQUAL J N)
(EQUAL J 0)
(EQUAL (NTH G 0) 4)
(NOT (EQUAL (NTH L 0) 9))
(NOT (EQUAL (NTH L 0) 10))
(NOT (EQUAL (NTH L 0) 11)))
(EQUAL (NTH L 0) 12)).
This again simplifies, trivially, to:
T.
Case 1. (IMPLIES (AND (NOT (ZEROP N))
(NOT (LG (SUB1 N) L G))
(MEMBER J (NSET N))
(LG N L G)
(EQUAL (NTH G J) 4)
(NOT (EQUAL (NTH L J) 9))
(NOT (EQUAL (NTH L J) 10))
(NOT (EQUAL (NTH L J) 11)))
(EQUAL (NTH L J) 12)).
This simplifies, rewriting with CDR-CONS and CAR-CONS, and unfolding the
definitions of ZEROP, NSET, MEMBER, LG-AT-N, AT, LG-3-AT-N, and LG, to:
(IMPLIES (AND (NOT (EQUAL N 0))
(NUMBERP N)
(NOT (LG (SUB1 N) L G))
(EQUAL J N)
(EQUAL J 0)
(EQUAL (NTH G 0) 4)
(NOT (EQUAL (NTH L 0) 9))
(NOT (EQUAL (NTH L 0) 10))
(NOT (EQUAL (NTH L 0) 11)))

Name the above subgoal *1.
Perhaps we can prove it by induction. There is only one plausible

Linear arithmetic, the lemmas COUNT-NUMBERP and COUNT-NOT-LESSP, and the

to the well-founded relation LESSP in each induction step of the scheme. The
above induction scheme produces the following three new formulas:

which we would normally push and work on later by induction. But if we must
use induction to prove the input conjecture, we prefer to induct on the
original formulation of the problem. Thus we will disregard all that we
have previously done, give the name *1 to the original input, and work on it.
So now let us return to:
(IMPLIES (MEMBER (ADD1 X) (NSET (SUB1 N)))

Linear arithmetic, the lemmas COUNT-NUMBERP and COUNT-NOT-LESSP, and the
definition of ZEROP inform us that the measure (COUNT X) decreases according
