Proof step 44 from proof push-corr (previous step)

i→n(i0) + i→n(i1) = n0 % # ar + # ar, i→n(i0) + n = n0 + # ar, n0 % # ar < n0 + # ar, n0 % # ar < # ar, 0 < i1, n < i→n(i1), 0 ≤ i0 + i1, inv(mk(ar[n0 % # ar, a], n→i(# ar), i0, i1 + 1)), i1 < n→i(# ar), inv(mk(ar, n→i(# ar), i0, i1)), i0 < n→i(# ar), i1 ≤ n→i(# ar), 0 ≤ i0, 0 ≤ (i0 + i1) % n→i(# ar) ⊦ i1 = 0, # ar = 1, ar[n0 % # ar] = a

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 31:
⊦ m < n → m % n = m
Proof step 43:
¬ n0 < # ar, i→n(i0) + i→n(i1) = n0 % # ar + # ar, i→n(i0) + n = n0 + # ar, n0 % # ar < n0 + # ar, n0 % # ar < # ar, 0 < i1, n < i→n(i1), 0 ≤ i0 + i1, inv(mk(ar[n0 % # ar, a], n→i(# ar), i0, i1 + 1)), i1 < n→i(# ar), inv(mk(ar, n→i(# ar), i0, i1)), i0 < n→i(# ar), i1 ≤ n→i(# ar), 0 ≤ i0, 0 ≤ (i0 + i1) % n→i(# ar) ⊦ i1 = 0, # ar = 1, ar[n0 % # ar] = a
