Proof step 16 from proof getintarray-at (previous step)

n < # getintarray(r, i, j, st), 0 < j ⊦ (getintarray(r, i, j, st)[n]) = st[r -- (i + n→i(n)) '] .intval

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ getintarray(r, i, j, st) = intvalues(getarray(r, i, j, st))
Proof step 15:
n < # intvalues(getarray(r, i, j, st)), 0 < j ⊦ (intvalues(getarray(r, i, j, st))[n]) = st[r -- (i + n→i(n)) '] .intval

Rule argument

[crewrite-arg: getintarray, F, [st, j, i, r] → [st, j, i, r]]
