Proof step 6 from proof int2bytes-one (previous step)

¬(~128 ≤ i ∧ i < 128), # int2bytes(i) = 1 ⊦ ¬ i < ~128 ∧ ¬ 127 < i, ¬ i < 0 ∧ ¬ 127 < i

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 7:
# int2bytes(i) = 1 ⊦ ¬ i < ~128 ∧ ¬ 127 < i, ¬ i < 0 ∧ ¬ 127 < i, ¬ i < ~128 ∧ ¬ 128 ≤ i

Rule argument

Additional information

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