Proof step 5 from proof bcompl-size-01 (previous step)

# int2bits(i) < # sgn(bitsinvert(int2bits(i))) ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 6:
⊦ bits ≠ [] → # sgn(bitsinvert(bits)) = # sgn(bits)

Rule argument

seq: ⊦ bits ≠ [] → # sgn(bitsinvert(bits)) = # sgn(bits) subst: [bits] → [int2bits(i)] rotate: F spec: bitopsaux inst: name: bitsinvert-size

Additional information

Used simplifier rules: ⊦ int2bits(j) ≠ [];% ⊦ sgn(int2bits(i)) = int2bits(i);% ⊦ ¬ n < n; Used terms: int2bits(i)
