Proof step 13 from proof putbar-byte (conclusion)

⊦ i ≤ j ∧ j < i + n→i(# bytes) → (putByteArray(bytes, r, i, st)[r -- j ']) = byteval(bytes[i→n(j - i)])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 12:
j < i + n→i(# bytes), i ≤ j ⊦ (putByteArray(bytes, r, i, st)[r -- j ']) = byteval(bytes[i→n(j - i)]), bytes = []

Rule argument
