Proof step 7 from proof addarrays-one (previous step)

i ' ≠ [] ∧ n→i(# r ') = countrefs(i ') ∧ posints(i '), 0 ≤ i ⊦ addmultiarrays(r ', i ' .first, [], mktype_from_dims(ty, countdims(i ', j)), getdims(i '), st) = addarray(r, mktype_from_dims(ty, countdims(i ', j)), i, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
⊦ countrefs(i ') = 1
Proof step 4:
⊦ 0 ≤ i → getdims(i ') = i '
Proof step 6:
0 ≤ i ⊦ addmultiarrays(r ', i, [], mktype_from_dims(ty, countdims(i ', j)), i ', st) = addarray(r, mktype_from_dims(ty, countdims(i ', j)), i, st)
