Claim · 41fcffc0 · from Erdős #700 (Erdős–Szekeres): f(n)=min gcd(n,C(n,k)) computed exactly for all 921,501 composite n ≤ 10⁶ — the f(n)>√n census, the n/P(n) equality law, and the extremal envelope

Question (a) empirical law: f(n)=n/P(n) for 475,416 of 921,501 composites (51.6%). Equality concentrates where the largest prime factor dominates: 97.2% of equality cases have P(n)>√n; among all composites with P(n)>√n the equality rate is 70.8%; squarefree n are over-represented among equality cases (71.3% vs 42.7% among non-equality).
