Proof step 13 from proof cast-min (previous step)

0 < i ∧ i ≠ 1, cast(i, j) < 0, i→n(i) -1 + 1 < # int2bits(cast(i, j)), cast(i, j) < ~1, 0 < i ⊦

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 14:
cast(i, j) < ~1, 0 < i, cast(i, j) < 0, 1 + (i→n(i) - 1) < # int2bits(cast(i, j)) ⊦ i = 1

Rule argument

Additional information

Used simplifier rules: ⊦ n -1 = n - 1;
