 A095365 Primes p such that f(q) < f(p) for all primes q < p, where f(p) = lcm(2-1, 3-1, 5-1, 7-1, 11-1, ..., p-1). 2

 OFFSET 1,1 COMMENTS A058255 gives the values of f(p) for the primes p in this sequence. The odd primes in this sequence seem to be the only values appearing in A095366. LINKS EXAMPLE 13 is not a member of this sequence because f(11) = f(13) = 60.
