Proof step 9 from proof getbar-3rec (previous step)

0 ≤ i0 ⊦ bytevalues(getarray(r, i, i0 + 3, st)) = st[r -- i '] .byteval ' + st[r -- (i + 1) '] .byteval ' + st[r -- (i + 2) '] .byteval ' + bytevalues(getarray(r, i + 3, i0, st))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
0 < j ⊦ getarray(r, i, j, st) = st[r -- i '] ' + getarray(r, i + 1, j - 1, st)
Proof step 8:
0 < i0 + 3, 0 ≤ i0 ⊦ bytevalues(st[r -- i '] ' + getarray(r, i + 1, i0 + 3 - 1, st)) = st[r -- i '] .byteval ' + st[r -- (i + 1) '] .byteval ' + st[r -- (i + 2) '] .byteval ' + bytevalues(getarray(r, i + 3, i0, st))

Rule argument

[crewrite-arg: getarray-offset-02 , F , [st, j, i, r] → [st, i0 + 3, i, r] ]
