Proof step 20 from proof pot2-est-div6 (previous step)

i0 = i1 + 1, 0 < i0, j0 < 6, 0 < (2 + i0) * 6 + j0, (2 ^ i1 * 2) * 2 ≤ 3 * (3 + i0), 4 * 2 ^ i1 * 2 ≤ (2 + i0) * 6 + j0 + 1, 0 ≤ i0, 36 ≤ (2 + i0) * 6 + j0, 0 ≤ j0 ⊦

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 21:
0 < (3 + i1) * 6 + j0, j0 < 6, 0 ≤ i1, 4 * 2 ^ i1 ≤ 3 * (4 + i1), 8 * 2 ^ i1 ≤ (3 + i1) * 6 + j0 + 1, 36 ≤ (3 + i1) * 6 + j0, 0 ≤ j0 ⊦
