Proof step 13 from proof subarray-copy (previous step)

n < m1, n < # copy(ar1, m0, mkarray(m1), 0, m1), m0 + m1 ≤ # ar1 ⊦ copy(ar0, n0, ar1, n3 + m0, n2)[n + m0] = (n < n3 ∨ n3 + n2 ≤ n ⊃ copy(ar1, m0, mkarray(m1), 0, m1)[n];ar0[n + n0 - n3])

And obtained the following new goals

Proof step 14:
n < m1, m0 + m1 ≤ # ar1 ⊦ copy(ar0, n0, ar1, n3 + m0, n2)[n + m0] = (n < n3 ∨ n3 + n2 ≤ n ⊃ copy(ar1, m0, mkarray(m1), 0, m1)[n];ar0[n + n0 - n3])

Rule argument
