Proof step 19 from proof divides-prime (previous step)

i0 < 0, i < 0, 2 ≤ i0 * i, 1 < abs(i0) ∧ abs(i0) < i0 * i → ¬ abs(i0) | i0 * i, ∀ i1. 1 < i1 ∧ i1 < i0 * i → ¬ i1 | i0 * i ⊦ ~1 = i, ~1 = i0, i = 0, i0 = 0

And obtained the following new goals

Proof step 20:
i < 0, i0 < 0, 2 ≤ i0 * i, 1 < ~ i0 ∧ ~ i0 < i0 * i → ¬ ~ i0 | i0 * i, ∀ i1. 1 < i1 ∧ i1 < i0 * i → ¬ i1 | i0 * i ⊦ ~1 = i0, ~1 = i, i = 0, i0 = 0
