Proof step 12 from proof pot2-est-div6 (previous step)

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

And obtained the following new goals

Proof step 13:
j0 < 6, 0 ≤ i1, 0 < (i1 + 1) * 6 + j0, (2 ^ (i1 - 1) * 2) * 2 ≤ ((i1 + 1) * 6 + j0) + 1, 36 ≤ (i1 + 1) * 6 + j0, 0 ≤ j0, 2 ^ (i1 - 1) * 2 ≤ 3 * (2 + i1), 0 < i1 ⊦
