Proof step 63 from proof isSquare-mult-aux (previous step)

max_prime_divisor(j0) ≠ 0, max_prime_divisor(j0) * i0 = j0, i0 * i0 = i1 * i1 * j, prime(max_prime_divisor(j0)), 0 < j, 0 < j0, 0 < max_prime_divisor(j0) * i1, ∀ j1, j, i. i→n(j1) < i→n(j0) → j1 * j1 = j * i * i ∧ 0 < j1 ∧ 0 < j ∧ 0 < i → i = 0 ∨ isSquare(j) ⊦ i0 * i0 = j * i1 * i1 ∧ 0 < i0 ∧ 0 < j ∧ 0 < i1, max_prime_divisor(j0) = 0, i1 = 0, isSquare(j), prime(j0)
