Proof step 16 from proof byte-law-neg (previous step)

i < 0 ∧ ~128 ≤ i % 256, i < ~128, i < 0 ⊦ i2b(~ i) = i2b(~(i % 256))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 17:
~128 ≤ i % 256, i < ~128, i < 0, i < i % 256 ⊦ i2b(~ i) = i2b(~(i % 256))

Rule argument
