Proof step 4 from proof int2bits-lelen-03 (previous step)

i < 0, i < ~1, i < 0 ⊦ # int2bits(~ i - 1) ≤ m ↔ ¬ i + 2 ^ (n→i(m) - 1) < 0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 5:
i < ~1, i < 0 ⊦ # int2bits(~(i + 1)) ≤ m ↔ ¬ i + 2 ^ (n→i(m) - 1) < 0

Rule argument

Additional information

Used simplifier rules: ⊦ ~ i - j = ~(i + j);
