Proof step 25 from proof putBar-lastrec (previous step)

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

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 24:
⊦ putByteArray(bytes + by ', r, i, st) = (putByteArray(bytes, r, i, st)[r -- (i + n→i(# bytes)) ', byteval(by)])
