Proof step 17 from proof countrefs-getdims-01 (previous step)

# (i ' + getdims(ints)) > 1 ∧ (i ' + getdims(ints)) .first ≤ 0 ⊦ 1 = countrefs(i ' + ints), ints = []

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 14:
⊦ getdims(ints) = [] ↔ ints = []
Proof step 16:
i ≤ 0 ⊦ 1 = countrefs(i ' + ints), ints = []

Rule argument
