Proof step 19 from proof fits-law-band-02 (previous step)

s2i(sho1) < 0, 0 ≤ band(s2i(sho1), s2i(sho2)), 0 < band(s2i(sho1), s2i(sho2)), 32768 ≤ band(s2i(sho1), s2i(sho2)) ⊦ band(s2i(sho1), s2i(sho2)) = s2i(i2s(band(s2i(sho1), s2i(sho2))))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 20:
⊦ 0 ≤ i ∧ i < i0 → ¬ i0 ≤ band(j, i)
Proof step 21:
¬(0 ≤ s2i(sho2) ∧ s2i(sho2) < 32768), s2i(sho1) < 0, 0 ≤ band(s2i(sho1), s2i(sho2)), 0 < band(s2i(sho1), s2i(sho2)), 32768 ≤ band(s2i(sho1), s2i(sho2)) ⊦ band(s2i(sho1), s2i(sho2)) = s2i(i2s(band(s2i(sho1), s2i(sho2))))

Rule argument

seq: ⊦ 0 ≤ i ∧ i < i0 → ¬ i0 ≤ band(j, i) subst: [i, j, i0] → [s2i(sho2), s2i(sho1), 32768] rotate: F spec: intops inst: name: band-max-06
