Proof step 5 from proof int2bytes-len-one-01 (previous step)

¬(~128 ≤ i ∧ i ≤ 127), # int2bytes(i) = 1 ⊦ i = b2i(i2b(i))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 6:
# int2bytes(i) = 1 ⊦ i = b2i(i2b(i)), ¬ i < ~128 ∧ ¬ 127 < i

Rule argument

Additional information

Used simplifier rules: ⊦ ¬ i ≤ j ↔ j < i;
