Proof step 4 from proof prime-divides-pot (previous step)

0 < j0, i * j = i0 ^ j0 -1 * i0, prime(i), 0 ≤ j0 ⊦ i | i0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 5:
i * j = i0 ^ (j0 - 1) * i0, prime(i), 0 ≤ j0, 0 < j0 ⊦ i | i0

Rule argument

Additional information

Used simplifier rules: forward-le-05: ⊦ i < j ∧ 0 ≤ i → 0 < j; (forward) from specification int-abs%sub-pred: ⊦ i -1 = i - 1; from specification int-abs
