Proof step 12 from proof mod-ls-same-01 (previous step)

0 ≤ i ⊦ i % j < i ↔ 0 < i ∧ (abs(j) = 1 ∨ abs(j) ≤ i), i = 0, j = 0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 13:
0 < i ⊦ i % j < i ↔ abs(j) = 1 ∨ abs(j) ≤ i, i = 0, j = 0

Rule argument

Additional information

Used simplifier rules: forward-le-05: ⊦ i < j ∧ 0 ≤ i → 0 < j; (forward) from specification int-abs% ⊦ i ≠ j → (i ≤ j ↔ i < j); (s)
