Proof step 2 from proof int2bits-lslen-10 (previous step)

2 ^ n→i(# int2bits(~ j)) + j < 0 ⊦

User applied rule insert lemma

And obtained the following new goals

Proof step 3:
⊦ ¬ 2 ^ n→i(# int2bits(~ j)) + j ≤ 0
Proof step 4:
¬ 2 ^ n→i(# int2bits(~ j)) + j ≤ 0, 2 ^ n→i(# int2bits(~ j)) + j < 0 ⊦

Rule argument

name: int2bits-lelen-07 subst: [j] → [j]
