Proof step 5 from proof short-law-neg (previous step)

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

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 6:
0 < i ⊦ cast(i, ~ j) = cast(i, ~ cast(i, j))
Proof step 7:
0 < 16 ⊦ i2s(cast(16, ~ cast(16, i))) = i2s(~ cast(16, i))

Rule argument

seq: 0 < i ⊦ cast(i, ~ j) = cast(i, ~ cast(i, j)) subst: [j, i] → [i, 16] rotate: F spec: intops inst: name: cast-law-neg

Additional information

Used terms: i, 16
