Proof step 2 from proof pdiv-ls (previous step)

i / j < j0, i0 ≤ i, j0 ≤ i0 / j, i / j < i0 / j, 0 < j ⊦

User applied rule insert lemma

And obtained the following new goals

Rule argument

spec: int-div inst: name: lsfc-01 seq: 0 < i0 ⊦ i / i0 < j / i0 → i < j subst: [i0, i, j] → [j, i, i0] flags: current, []
