Proof step 12 from proof max_prime_divisor-nls-02 (previous step)

j < i, j < max_prime_divisor(i / j), 0 < i, prime(j), j | i, 2 ≤ i, 0 ≤ i, 2 ≤ i / j → prime(j0) ∧ j0 | i / j ∧ j0 < i / j ∧ (∀ j1. j0 < j1 ∧ j1 < i / j ∧ prime(j1) → ¬ j1 | i / j), ∀ j0. j < j0 ∧ j0 < i ∧ prime(j0) → ¬ j0 | i ⊦ prime(i / j), prime(i)

Proof step 13:
0 < i, j < max_prime_divisor(i / j), j < i, prime(j), j | i, 0 ≤ i, 2 ≤ i, 2 ≤ i / j, 2 ≤ i / j → prime(j0) ∧ j0 | i / j ∧ j0 < i / j ∧ (∀ j1. j0 < j1 ∧ j1 < i / j ∧ prime(j1) → ¬ j1 | i / j), ∀ j0. j < j0 ∧ j0 < i ∧ prime(j0) → ¬ j0 | i ⊦ prime(i), prime(i / j)
Proof step 24:
0 < i, j < max_prime_divisor(i / j), j < i, prime(j), j | i, 0 ≤ i, 2 ≤ i, 2 ≤ i / j → prime(j0) ∧ j0 | i / j ∧ j0 < i / j ∧ (∀ j1. j0 < j1 ∧ j1 < i / j ∧ prime(j1) → ¬ j1 | i / j), ∀ j0. j < j0 ∧ j0 < i ∧ prime(j0) → ¬ j0 | i ⊦ prime(i), prime(i / j), 2 ≤ i / j
