Proof step 36 from proof getarray-put=set (previous step)

i0 = i1 + i, i0 < i + j, i ≤ i0, 0 < j ⊦ getarray(r, i, j, st[r -- i0 ', val]) = (getarray(r, i, j, st)[i→n(i1), val])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 35:
0 < j, i1 < j, 0 ≤ i1 ⊦ getarray(r, i, j, st[r -- (i1 + i) ', val]) = (getarray(r, i, j, st)[i→n(i1), val])
