Proof step 21 from proof arr2list-put (previous step)

n < # ar, n < # arr2list(ar, m0), m0 + 1 < # ar, n ≤ m0, ∀ n, ar, bv. n < # ar ∧ n ≤ m0 ∧ m0 < # ar → (arr2list(ar, m0)[n, bv]) = arr2list(ar[n, bv], m0) ⊦ arr2list(ar, m0) = [], m0 + 1 = n, (arr2list(ar, m0)[n, bv]) = arr2list(ar[n, bv], m0)

Heuristic quantifier closing applied rule all left

And closed the goal!

Rule argument

[EXRARG : pos: left 5, [QUANTTERMLIST : (n, ar, bv)]]
