Proof step 10 from proof getdims-zeroin (previous step)

0 ∈ getdims(i ' + ints0) .butlast, 0 ∈ getdims(i ' + ints0), ints0 ≠ [] → ¬ 0 ∈ getdims(ints0) .butlast ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ 0 < j → getdims(j ' + ints) = j ' + getdims(ints)
Proof step 3:
⊦ j ≤ 0 → getdims(j ' + ints) = 0 '
Proof step 9:
0 < i, 0 ∈ (i ' + getdims(ints0)) .butlast, 0 ∈ i ' + getdims(ints0), ints0 ≠ [] → ¬ 0 ∈ getdims(ints0) .butlast ⊦

Rule argument

[crewrite-arg: getdims-rec, F, [ints, j] → [ints0, i]]
