Proof step 77 from proof addarray-put-01 (previous step)

0 < j, 0 ≤ i0, 0 ≤ i0 + j, i ≤ j + i0, 0 ≤ i ⊦ j = 0, i = j, r -- i ' ∈ addarray(r, ty, i0 + j + 1, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 76:
⊦ 0 ≤ j ∧ j < i → r -- j ' ∈ addarray(r, ty, i, st)

Rule argument

[crewrite-arg: in-1dim-16 , F , [st, i, ty, j, r] → [st, i0 + j + 1, ty, i, r] ]
