Proof step 5 from proof le-2pot-01 (previous step)

i0 ≤ 2 ^ i, 0 ≤ j0, j0 < 2, 0 ≤ i, 0 ≤ i0 ⊦ i0 * 2 + j0 ≤ 2 ^ (i + 1) + 1

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 6:
i0 ≤ 2 ^ i, 0 ≤ j0, j0 < 2, 0 ≤ i, 0 ≤ i0, 0 ≤ 2 ^ i ⊦ i0 * 2 + j0 ≤ 2 ^ (i + 1) + 1

Rule argument
