The first few values are 1, 2, 2, 4, 2, 4, 2, 4, 6, 2, 6, 4, 2, 4, 6, 6, ... (OEIS A001223). Rankin has shown that
for infinitely many n and for some constant c (Guy 1994). At a March 2003 meeting on elementary and analytic number in Oberwolfach, Germany, Goldston and Yildirim presented an attempted proof that
(Montgomery 2003). Unfortunately, this proof turned out to be flawed.
An integer n is called a jumping champion if n is the most frequently occurring difference between consecutive primes n<=N for some N (Odlyzko et al.).
