Proof step 23 from proof max-app (previous step)

min(i, i0) ' = [] ∨ x2 = [] ∨ max(min(i, i0) ' + x2) = max(max(min(i, i0) '), max(x2)), min(i, i0) < i1, ∀ x0, y0. # x0 + # y0 < # (i + i0 + i1 + x2) + # y → (true → x0 = [] ∨ y0 = [] ∨ max(x0 + y0) = max(max(x0), max(y0))) ⊦ y = [], max(i1, max(max(min(i, i0) ' + x2 + y), max(i, i0))) = max(i1, max(max(min(i, i0) ' + x2), max(max(y), max(i, i0))))

Proof step 18:
⊦ max(i ') = i
Proof step 22:
min(i, i0) < i1, x2 = [] ∨ max(min(i, i0) ' + x2) = max(max(x2), min(i, i0)), ∀ x0, y0. # x0 + # y0 < # (i + i0 + i1 + x2) + # y → (true → x0 = [] ∨ y0 = [] ∨ max(x0 + y0) = max(max(x0), max(y0))) ⊦ y = [], max(i1, max(max(min(i, i0) ' + x2 + y), max(i, i0))) = max(i1, max(max(min(i, i0) ' + x2), max(max(y), max(i, i0))))
