Proof step 15 from proof fits-law-bxor-01 (previous step)

⊦ bor(band(s2i(sho1), bcompl(b2i(by2))), band(bcompl(s2i(sho1)), b2i(by2))) = s2i(i2s(bor(band(s2i(sho1), bcompl(b2i(by2))), band(bcompl(s2i(sho1)), b2i(by2))))), s2i(i2s(bcompl(b2i(by2)))) = bcompl(b2i(by2)), s2i(i2s(band(s2i(sho1), bcompl(b2i(by2))))) = band(s2i(sho1), bcompl(b2i(by2))) ∧ s2i(i2s(band(bcompl(s2i(sho1)), b2i(by2)))) = band(bcompl(s2i(sho1)), b2i(by2))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 16:
⊦ i ∈short → s2i(i2s(bcompl(i))) = bcompl(i)

Rule argument

name: bcompl-sis rotate: F subst: [i] → [b2i(by2)]
