Proof step 14 from proof max-snd-nls (previous step)

((maxenc(m) + 2) * maxenc(m) + maxenc(m)) % 2 = 0, (maxenc(m) + (maxenc(m) * maxenc(m) + maxenc(m)) / 2) * 2 < (maxenc(m) + 2) * maxenc(m) + maxenc(m), maxenc(m) + (maxenc(m) * maxenc(m) + maxenc(m)) / 2 < m, m ≤ ((maxenc(m) + 2) * maxenc(m) + maxenc(m)) / 2, (maxenc(m) * maxenc(m) + maxenc(m)) / 2 ≤ m ⊦ (maxenc(m) + 2) * maxenc(m) + maxenc(m) = 0, maxenc(m) = 0

And obtained the following new goals

Proof step 15:
(maxenc(m) + (maxenc(m) * maxenc(m) + maxenc(m)) / 2) * 2 < (maxenc(m) + 2) * maxenc(m) + maxenc(m), maxenc(m) + (maxenc(m) * maxenc(m) + maxenc(m)) / 2 < m, m ≤ ((maxenc(m) + 2) * maxenc(m) + maxenc(m)) / 2, (maxenc(m) * maxenc(m) + maxenc(m)) / 2 ≤ m ⊦ maxenc(m) = 0
