Proof step 17 from proof max-snd-nls (previous step)

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

And obtained the following new goals

Proof step 18:
maxenc(m) + 2 * (maxenc(m) * maxenc(m) + maxenc(m)) / 2 < (maxenc(m) + 2) * maxenc(m), maxenc(m) + (maxenc(m) * maxenc(m) + maxenc(m)) / 2 < m, (maxenc(m) * maxenc(m) + maxenc(m)) / 2 ≤ m, m ≤ ((maxenc(m) + 2) * maxenc(m) + maxenc(m)) / 2 ⊦ maxenc(m) = 0
