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

0 ≤ i, 0 ≤ j ⊦ j / 2 ≤ 2 ^ i ↔ j ≤ 2 ^ (i + 1) + 1

User applied rule insert elim lemma

And obtained the following new goals

Proof step 3:
j = i0 * 2 + j0 ∧ 0 ≤ j0 ∧ j0 < 2 ∧ 0 < 2, 0 ≤ i, 0 ≤ j ⊦ i0 ≤ 2 ^ i ↔ j ≤ 2 ^ (i + 1) + 1

Rule argument

spec: int-div inst: name: div-elim-pos seq: ⊦ 0 < j ∧ 0 ≤ i → ( i0 = i / j ∧ j0 = i % j ↔ i = i0 * j + j0 ∧ 0 ≤ j0 ∧ j0 < j) subst: [i, j, i0, j0] → [j, 2, i0, j0] flags:

Additional information

Used simplifier rules: ⊦ 0 < j ∧ 0 ≤ i → (i0 = i / j ∧ j0 = i % j ↔ i = i0 * j + j0 ∧ 0 ≤ j0 ∧ j0 < j); (elim) Used terms: j, 2, i0, j0
