Proof step 2 from proof max_exp-fac-smaller (previous step)

prime(i), j < i, 0 < j, 0 < i, 1 < i ⊦ max_exp(i, fac(j)) = 0

User applied rule induction

And obtained the following new goals

Proof step 3:
prime(i) ∧ j < i ∧ 0 < j ∧ 0 < i ∧ 1 < i, ∀ j0, i. i→n(j0) < i→n(j) → prime(i) ∧ j0 < i ∧ 0 < j0 ∧ 0 < i ∧ 1 < i → max_exp(i, fac(j0)) = 0 ⊦ max_exp(i, fac(j)) = 0

Rule argument

indvar: i→n(j) wfpred: <

Additional information

Used simplifier rules: <; (wellfounded) Used terms: i→n(j)
