Proof step 1 from proof bytes2int-011x (conclusion)

⊦ bytes2int(i2b(0) ' + mklist(i2b(~1), n)) = 2 ^ (8 * n→i(n)) - 1

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ 2 ^ (8 * n→i(n)) = bytes2int(i2b(0) ' + mklist(i2b(~1), n)) + 1

Rule argument

Additional information

Used simplifier rules: ⊦ i - j = i0 ↔ i = i0 + j;
