Proof step 1 from proof short-is-cast-01 (conclusion)

⊦ i2s(i) = i2s(cast(16, i))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ i2s(i) = i2s(j) ↔ s2i(i2s(i)) = s2i(i2s(j))
Proof step 3:
⊦ s2i(i2s(i)) = s2i(i2s(cast(16, i)))

Rule argument

name: short-inj rotate: F subst: [j, i] → [cast(16, i), i]

Additional information

Used terms: cast(16, i), i
