Proof step 5 from proof getbar-restn (previous step)

¬ n ≤ # getbytearray(r, st), n→i(n) ≤ st[r -- _length] .intval ⊦ # restn(n, getbytearray(r, st)) = i→n(st[r -- _length] .intval - n→i(n))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 4:
# getbytearray(r, st) < n, n→i(n) ≤ st[r -- _length] .intval ⊦ # restn(n, getbytearray(r, st)) = i→n(st[r -- _length] .intval - n→i(n))

Rule argument
