Proof step 1 from proof bytes2int-size-val-02 (conclusion)

⊦ ∃ by, bytes. 0 < b2i(by) ∧ bytes2int(by ' + bytes) = 2 ^ ((n→i(# bytes) + 1) * 8 - 1) - 1

User applied rule exists right

And obtained the following new goals

Proof step 2:
⊦ 0 < b2i(i2b(127)) ∧ bytes2int(i2b(127) ' + mklist(i2b(~1), n)) = 2 ^ ((n→i(# mklist(i2b(~1), n)) + 1) * 8 - 1) - 1

Rule argument

pos: right 1 terms: i2b(127), mklist(i2b(~1), n) abort: F discard: T computed: F

Additional information

Used terms: i2b(127), mklist(i2b(~1), n)
