Smallest prime greater than 80

WebbIf so, let q be the smallest prime that divides such a composite number. We have n2 + n + p ≡ 0 (mod q). This means (2n + 1)2 ≡ Δ (mod q), so we know Δ is a quadratic residue. Next n2 + n + p ≤ (p − 1)2 + 1. So, the smallest prime factor is smaller than p − 1, and q < p, so q < − Δ. Let's see, the two roots of n2 + n + p (mod q) add up to q − 1.
