Proof step 4 from proof mod-twoodd-01 (previous step)

0 ≤ j0, 0 < j ⊦ (2 * j0 + 1) % (2 * j) = j0 % j * 2 + 1

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: int-div inst: name: mod-twoodd seq: 0 ≤ i, 0 < j ⊦ (2 * i + 1) % (2 * j) = i % j * 2 + 1 subst: [j, i] → [j, j0] flags: rewrite, current

Additional information

Used simplifier rules: zero-gels-04: ⊦ i ≤ 0 ∧ 0 ≤ j → i ≤ j; from specification int-abs Used terms: j, j0
