Proof step 4 from proof short-law-compl (previous step)

⊦ i2s(~(i + 1)) = i2s(~(cast(16, i) + 1))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 5:
⊦ i2s(i) = i2s(cast(16, i))
Proof step 6:
⊦ i2s(~(i + 1)) = i2s(cast(16, ~(cast(16, i) + 1)))

Rule argument

name: short-is-cast-01 rotate: F subst: [i] → [~(cast(16, i) + 1)]

Additional information

Used terms: ~(cast(16, i) + 1)
