Proof step 7 from proof short-law-and-one (previous step)

⊦ cast(16, band(j, j0)) = cast(16, band(cast(16, j), j0))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 8:
0 < i ⊦ cast(i, band(j, j0)) = cast(i, band(cast(i, j), j0))

Rule argument

seq: 0 < i ⊦ cast(i, band(j, j0)) = cast(i, band(cast(i, j), j0)) subst: [j0, j, i] → [j0, j, 16] rotate: F spec: intops inst: name: cast-law-and-one

Additional information

Used simplifier rules: ⊦ band(i, j) = band(j, i); Used terms: j0, j, 16
