Proof step 2 from proof max_prime_divisor-not-zero (previous step)

max_prime_divisor(i) = 0, 2 ≤ i, 0 ≤ i, 0 < i ⊦ prime(i)

User applied rule insert lemma

And obtained the following new goals

Rule argument

spec: inst: name: max_prime_divisor-nle-zero seq: ⊦ ¬ prime(i) ∧ 2 ≤ i → ¬ max_prime_divisor(i) ≤ 0 subst: [i] → [i] flags: current, []
