n4 < n0 + n3 + m0, n1 + n4 < # ar0, ((n3 + n1) + m0) + n0 ≤ # ar0, (n3 + n2 + m0) + n0 ≤ # ar2, (n3 + n1) + m0 ≤ # ar0, (n3 + n2) + m0 ≤ # ar2, n + m0 ≤ # ar, n2 + n3 ≤ # ar2, n1 + n3 ≤ # ar0, n3 + m0 ≤ n4, ∀ n. n < n0 → ar2[(n3 + n2 + m0) + n] = ar0[((n3 + n1) + m0) + n], ∀ n4. n4 < m0 → ar2[(n3 + n2) + n4] = ar[n + n4], ∀ n. n < n3 → ar2[n2 + n] = ar0[n1 + n] ⊦ ar2[n2 + n4] = ar0[n1 + n4]
