Proof step 5 from proof getdims-posints (previous step)

posints(ints0) → posints(getdims(ints0)), posints(i + ints0) ⊦ posints(getdims(i + ints0))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 4:
posints(ints0), posints(getdims(ints0)), 0 ≤ i ⊦ posints(getdims(i ' + ints0))

Rule argument
