Proof step 6 from proof max-app (previous step)

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

And obtained the following new goals

Proof step 3:
⊦ max(i ') = i
Proof step 5:
max(min(i, i0) ' + x2) = max(max(x2), min(i, i0)), ∀ x0, y0. # x0 + # y0 < # (i + []) + # (i0 + x2) → (true → x0 = [] ∨ y0 = [] ∨ max(x0 + y0) = max(max(x0), max(y0))) ⊦ max(max(i, i0), max(max(x2), min(i, i0))) = max(max(i0 ' + x2), i), x2 = []
