Proof step 2 from proof bytes2int-size-val-01 (previous step)

⊦ ∃ by, bytes. ¬ 0 ≤ b2i(by) ∧ 2 ^ ((n→i(# bytes) + 1) * 8 - 1) = bytes2int(i2b(0) ' + by ' + bytes)

User applied rule exists right

And obtained the following new goals

Proof step 3:
⊦ ¬ 0 ≤ b2i(i2b(~128)) ∧ 2 ^ ((n→i(# mklist(i2b(0), n)) + 1) * 8 - 1) = bytes2int(i2b(0) ' + i2b(~128) ' + mklist(i2b(0), n))

Rule argument

pos: right 1 terms: i2b(~128), mklist(i2b(0), n) abort: F discard: T computed: F

Additional information

Used terms: i2b(~128), mklist(i2b(0), n)
