Proof step 2 from proof int2bits-lslen-09 (
previous step
)
# int2bits(~ j) + 1 < # int2bits(~(j + 1)) ⊦
User applied rule insert rewrite lemma
And obtained the following new goals
Proof step 3
:
⊦ ~(i + 1) = ~ i - 1
Proof step 4
:
# int2bits(~ j) + 1 < # int2bits(~ j - 1) ⊦
Rule argument
seq: ⊦ ~(i + 1) = ~ i - 1 subst: [i] → [j] rotate: F spec: int-abs inst: name: minus-01
