Proof step 6 from proof bytes2int-len-one-02 (previous step)

b2i(by) < 0, 0 ≤ bytes2int(i2b(0) ' + by ' + bytes), bytes2int(i2b(0) ' + by ' + bytes) < 128 ⊦

User applied rule cut formula

And obtained the following new goals

Proof step 7:
bytes = [], b2i(by) < 0, 0 ≤ bytes2int(i2b(0) ' + by ' + bytes), bytes2int(i2b(0) ' + by ' + bytes) < 128 ⊦
Proof step 10:
b2i(by) < 0, 0 ≤ bytes2int(i2b(0) ' + by ' + bytes), bytes2int(i2b(0) ' + by ' + bytes) < 128 ⊦ bytes = []

Rule argument

fma: bytes = []

Additional information

Used formulas: bytes = []
