Proof step 32 from proof multi-refin (previous step)

# refs = i→n(countrefs(i ' + ints0)), i ≤ i0, 0 ≤ i, rk ∈ st, posints(ints0), 0 < i0, ∀ ty, acc, ints, i, st, rk, refs0. # refs0 < # refs → ( true → ( rk ∈ st ∧ # refs0 = i→n(countrefs(i ' + ints .rest)) ∧ ints ≠ [] ∧ 0 ≤ i ∧ posints(ints) ∧ ¬ 0 ∈ ints .butlast ∧ i ≤ ints .first → rk ∈ addmultiarrays(refs0, i, acc, ty, ints, st))) ⊦ ints0 = [], 0 = i0, rk ∈ addmultiarrays(refs, i, acc, ty, i0 ' + ints0, st), 0 ∈ ints0 .butlast

And obtained the following new goals

Proof step 2:
⊦ i = 0 ∧ # ints > 1 → addmultiarrays(refs, i, acc, ty, ints, st) = addarray(refs .first, mktype_from_dims(ty, n→i(# ints) - 1), mkjavavalues(acc), st)
Proof step 30:
¬ (i = 0 ∧ # (i0 ' + ints0) > 1), # refs = i→n(countrefs(i ' + ints0)), i ≤ i0, 0 ≤ i, rk ∈ st, posints(ints0), 0 < i0, ∀ ty, acc, ints, i, st, rk, refs0. # refs0 < # refs → ( true → ( rk ∈ st ∧ # refs0 = i→n(countrefs(i ' + ints .rest)) ∧ ints ≠ [] ∧ 0 ≤ i ∧ posints(ints) ∧ ¬ 0 ∈ ints .butlast ∧ i ≤ ints .first → rk ∈ addmultiarrays(refs0, i, acc, ty, ints, st))) ⊦ ints0 = [], 0 = i0, rk ∈ addmultiarrays(refs, i, acc, ty, i0 ' + ints0, st), 0 ∈ ints0 .butlast
Proof step 31:
⊦ countrefs(0 ' + ints) = 1
