Proof step 2 from proof bar-eq-sub (previous step)

getbytearray(r, i0, j0, st) = getbytearray(r0, i0, j0, st0), i0 ≤ i, i + j ≤ i0 + j0 ⊦ getbytearray(r, i, j, st) = getbytearray(r0, i, j, st0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ getbytearray(r, i, j, st) ≠ getbytearray(r0, i, j, st0) ∧ i0 ≤ i ∧ i + j ≤ i0 + j0 → getbytearray(r, i0, j0, st) ≠ getbytearray(r0, i0, j0, st0)

Rule argument

[crewrite-arg: bar-neq-soffset , F , [r, i, j, st, r0, st0, i0, j0] → [r, i, j, st, r0, st0, i0, j0] ]
