Proof step 6 from proof long-is-cast (previous step)

¬(0 < 64 ∧ ~(2 ^ (64 - 1)) ≤ i ∧ i < 2 ^ (64 - 1)), i ∈long ⊦ i = cast(64, i)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 7:
i ∈long ⊦ i = cast(64, i), ¬ i < ~9223372036854775808 ∧ ¬ 9223372036854775808 ≤ i

Rule argument

Additional information

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