Proof step 15 from proof cast-size-fits-01 (previous step)

0 < i, 0 ≤ i, 0 ≤ 2 ^ (i - 1), i→n(i) < # int2bits(~1) ⊦ cast(i, ~1) = ~1, # int2bits(~1) = 1

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

seq: ⊦ i + 1 = 0 → int2bits(i) = true ' subst: [i] → [~1] rotate: F spec: int2bits inst: name: int2bits-mone
