Proof step 11 from proof countrefs-getdims (previous step)

¬ 0 < i, countrefs(getdims(ints0)) = countrefs(ints0) ⊦ countrefs(getdims(i ' + ints0)) = countrefs(i ' + ints0)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 4:
⊦ j ≤ 0 → getdims(j ' + ints) = 0 '
Proof step 5:
⊦ countrefs(i ') = 1
Proof step 10:
countrefs(getdims(ints0)) = countrefs(ints0), i ≤ 0 ⊦ 1 = countrefs(i ' + ints0)

Rule argument
