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

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

User applied rule insert rewrite lemma

And obtained the following new goals

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

Rule argument

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

Additional information

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