 OFFSET 1,1 COMMENTS The first values of p are 3, 5, 7, 13, 41 from A163080. Subsequence of A163076 (primes of the form n\$ - 1). REFERENCES Peter Luschny, "Divide, swing and conquer the factorial and the lcm{1,2,...,n}", preprint, April 2008. LINKS Peter Luschny, Swinging Primes. EXAMPLE 3 and 3\$ - 1 = 5 are prime, so 5 is a member. MAPLE a := proc(n) select(isprime, [\$2..n]); select(isprime, map(x -> A056040(x)-1, %)) end: CROSSREFS Cf. A163074 through A163083.
