Proof step 15 from proof okarray-init-04 (previous step)

j ≤ n→i(# vals), is_bytevalue((vals + byteval(by) ')[i→n(j)]), j < n→i(# vals), 0 ≤ j, # vals ≤ i→n(j) ⊦ vals = [], r = jvmref, is_bytevalue(vals[i→n(j)])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 14:
0 ≤ i ⊦ m ≤ i→n(i) ↔ n→i(m) ≤ i

Rule argument
