Proof step 10 from proof fits-law-bxor-02 (previous step)

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

And obtained the following new goals

Proof step 11:
⊦ i ∈short ∧ j ∈short → s2i(i2s(band(i, j))) = band(i, j)
Proof step 12:
¬(s2i(sho1) ∈short ∧ bcompl(s2i(sho2)) ∈short) ⊦ 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))))), s2i(i2s(band(s2i(sho1), bcompl(s2i(sho2))))) = band(s2i(sho1), bcompl(s2i(sho2))) ∧ s2i(i2s(band(bcompl(s2i(sho1)), s2i(sho2)))) = band(bcompl(s2i(sho1)), s2i(sho2))
Proof step 17:
s2i(sho1) ∈short ∧ bcompl(s2i(sho2)) ∈short ⊦ 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))))), band(s2i(sho1), bcompl(s2i(sho2))) = band(s2i(sho1), bcompl(s2i(sho2))) ∧ s2i(i2s(band(bcompl(s2i(sho1)), s2i(sho2)))) = band(bcompl(s2i(sho1)), s2i(sho2))
