+ Smarandache-Radu triplets; integers n such that there are no primes between the smaller and larger of S(n) and S(n+1): 224, 2057, 265225, ... (Sloane's A015048; Radu 1994/1995, Begay 1997, Ibstedt 1997). The largest known Smarandache-Radu triplet is 270,329,975,921,205,253,634,707,051,822,848,570,391,313. Here S(n) is the Smarandache Function, i.e. the mallest integer such that S(n)! is divisible by n. [Weisstein]
