Proof step 50 from proof pot2-est-div6 (previous step)

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

User applied rule cut formula

And obtained the following new goals

Proof step 51:
0 < i0 * 6 + j0, j0 < 6, (i0 + 1) * 6 < 2 ^ i0, (i0 + 1) * 6 ≤ i0 * 6 + j0, 2 ^ i0 ≤ (i0 * 6 + j0) + 1, 36 ≤ i0 * 6 + j0, 0 ≤ j0, 0 ≤ i0 ⊦ (i0 * 6 + j0) + 1 ≤ i0 * 6 + 6

Rule argument

fma: (i0 * 6 + j0) + 1 ≤ i0 * 6 + 6

Additional information

Used simplifier rules: ⊦ i * j + i = i * (j + 1); (s)%associativity: ⊦ i * j * j0 = (i * j) * j0; from specification int-mult%commutativity: ⊦ i * j = j * i; from specification int-mult%add-a: ⊦ i + j + i0 = (i + j) + i0; from specification int-basic2%add-c: ⊦ i + j = j + i; from specification int-basic2% ⊦ i + 1 ≤ j ↔ i < j; (s)% ⊦ i ≤ j → ¬ j < i; (s) Used formulas: (i0 * 6 + j0) + 1 ≤ i0 * 6 + 6
