Proof step 18 from proof multi-newrefs (previous step)

# refs = i→n(countrefs(i ' + ints .rest)), list2set(refs) ∩ list2set(refs0) = ∅, posints(ints), i ≤ ints .first, 0 ≤ i, 0 ≤ ints .first ⊦ is_newref_list(refs0, addmultiarrays(refs, i, acc, ty, ints, st)) ↔ is_newref_list(refs0, st), ints = [], 0 ∈ ints .butlast

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 17:
ints = i0 + ints0, # refs = i→n(countrefs(i ' + ints0)), list2set(refs) ∩ list2set(refs0) = ∅, posints(ints), i ≤ i0, 0 ≤ i, 0 ≤ i0 ⊦ is_newref_list(refs0, addmultiarrays(refs, i, acc, ty, ints, st)) ↔ is_newref_list(refs0, st), ints = [], 0 ∈ ints .butlast
