Proof step 1 from proof int2bits-lslen (conclusion)

⊦ 0 < i → (# int2bits(i) < m ↔ i < 2 ^ (n→i(m) - 2))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

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

Rule argument

Additional information

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