Proof step 9 from proof uint2bits-falsein (previous step)

bitsinvert(bitsinvert(uint2bits(i))) = bitsinvert(bits + false '), 0 ≤ i, 0 < i, 1 < i ⊦ false ∈ bits

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 10:
⊦ bitsinvert(bitsinvert(bits)) = bits
Proof step 11:
uint2bits(i) = bitsinvert(bits + false '), 0 ≤ i, 0 < i, 1 < i ⊦ false ∈ bits

Rule argument

seq: ⊦ bitsinvert(bitsinvert(bits)) = bits subst: [bits] → [uint2bits(i)] rotate: F spec: bitopsaux inst: name: inv-inv
