Proof step 2 from proof all_prime_divisors-last (previous step)

⊦ all_prime_divisors(i) = [], all_prime_divisors(i).last = max_prime_divisor(i), prime(i)

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: inst: name: all_prime_divisors-rec seq: ⊦ 2 ≤ i ∧ ¬ prime(i) → all_prime_divisors(i) = all_prime_divisors(i / max_prime_divisor(i)) + max_prime_divisor(i) ' subst: [i] → [i] flags: rewrite, current
