Proof step 24 from proof fix2rest-last (previous step)

1 = # bytes0, 0 ≤ bytes2int(by ' + bytes0) ⊦ bytes0 = (by ' + bytes0).last '

Heuristic weak cut applied rule cut formula

And obtained the following new goals

Proof step 25:
1 = # bytes0, 0 ≤ bytes2int(by ' + bytes0) ⊦ bytes0 = [], bytes0 = (by ' + bytes0).last '

Rule argument

fma: bytes0 = []

Additional information

Used simplifier rules: ⊦ # [] = 0; Used formulas: bytes0 = []
