Proof step 20 from proof addarrays-fieldin (previous step)

n→i(# refs) = countrefs(i0 ' + ints0), posints(ints0), 0 ≤ i0 ⊦ fs ' = _length, fs ' = _type, r -- fs ' ∈ addmultiarrays(refs, i0, [], mktype_from_dims(ty, countdims(i0 ' + ints0, i)), getdims(i0 ' + ints0), st) ↔ r -- fs ' ∈ st

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ fs ' ≠ _type ∧ fs ' ≠ _length ∧ # refs = i→n(countrefs(i ' + ints .rest)) ∧ ints ≠ [] ∧ 0 ≤ i ∧ posints(ints) ∧ ¬ 0 ∈ ints .butlast ∧ i ≤ ints .first → (r -- fs ' ∈ addmultiarrays(refs, i, acc, ty, ints, st) ↔ r -- fs ' ∈ st)
Proof step 19:
¬ ( fs ' ≠ _type ∧ fs ' ≠ _length ∧ # refs = i→n(countrefs(i0 ' + getdims(i0 ' + ints0) .rest)) ∧ getdims(i0 ' + ints0) ≠ [] ∧ 0 ≤ i0 ∧ posints(getdims(i0 ' + ints0)) ∧ ¬ 0 ∈ getdims(i0 ' + ints0) .butlast ∧ i0 ≤ getdims(i0 ' + ints0) .first), n→i(# refs) = countrefs(i0 ' + ints0), posints(ints0), 0 ≤ i0 ⊦ fs ' = _length, fs ' = _type, r -- fs ' ∈ addmultiarrays(refs, i0, [], mktype_from_dims(ty, countdims(i0 ' + ints0, i)), getdims(i0 ' + ints0), st) ↔ r -- fs ' ∈ st
