Proof step 3 from proof int2bytes-rec-case (previous step)

¬ i < ~128 ∧ ¬ 128 ≤ i ⊦ int2bytes(i) = i2b(i) '

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 4:
i < 128, ~128 ≤ i ⊦ int2bytes(i) = i2b(i) '

Rule argument

Additional information

Used simplifier rules: ⊦ i ≤ j ∧ j < j0 → i < j0; (forward)% ⊦ ¬ i < j ↔ j ≤ i;% ⊦ ¬ i ≤ j ↔ j < i;
