Proof step 8 from proof getbar-putbar (previous step)

∀ r, r1, st. r ≠ r1 → getbytearray(r, putByteArray(bytes0, r1, st)) = getbytearray(r, st) ⊦ r ≠ r1 → getbytearray(r, putByteArray(by + bytes0, r1, st)) = getbytearray(r, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 7:
∀ r, r1, st. r ≠ r1 → getbytearray(r, putByteArray(bytes0, r1, st)) = getbytearray(r, st) ⊦ r = r1, getbytearray(r, putByteArray(by ' + bytes0, r1, st)) = getbytearray(r, st)

Rule argument
