Proof step 18 from proof fits-law-bor-02 (previous step)

⊦ s2i(i2s(band(bcompl(s2i(sho1)), bcompl(s2i(sho2))))) = band(bcompl(s2i(sho1)), bcompl(s2i(sho2))), bcompl(band(bcompl(s2i(sho1)), bcompl(s2i(sho2)))) = s2i(i2s(bcompl(band(bcompl(s2i(sho1)), bcompl(s2i(sho2)))))), s2i(i2s(bcompl(s2i(sho2)))) = bcompl(s2i(sho2))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 19:
⊦ i ∈short → s2i(i2s(bcompl(i))) = bcompl(i)

Rule argument

name: bcompl-sis rotate: F subst: [i] → [s2i(sho2)]

Additional information

Used simplifier rules: short2int-in: ⊦ s2i(sho) ∈short; Used terms: s2i(sho2)
