Proof step 3 from proof bar-eq-sub (previous step)

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

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
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)
