Proof step 1 from proof fits-law-bxor-02 (conclusion)

⊦ bxor(s2i(sho1), s2i(sho2)) = s2i(i2s(bxor(s2i(sho1), s2i(sho2))))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ bxor(i, j) = bor(band(i, bcompl(j)), band(bcompl(i), j))
Proof step 3:
⊦ bor(band(s2i(sho1), bcompl(s2i(sho2))), band(bcompl(s2i(sho1)), s2i(sho2))) = s2i(i2s(bor(band(s2i(sho1), bcompl(s2i(sho2))), band(bcompl(s2i(sho1)), s2i(sho2)))))

Rule argument

seq: ⊦ bxor(i, j) = bor(band(i, bcompl(j)), band(bcompl(i), j)) subst: [j, i] → [s2i(sho2), s2i(sho1)] rotate: F spec: intops inst: name: bxor-def-logic

Used terms: s2i(sho2), s2i(sho1)
