Appears in sequences

• Numbers k such that k! + 1 is prime.at n=21A002981
• Primes p such that the differences between the 5 consecutive primes starting with p are (2,6,4,2).at n=22A078948
• A088258 indexed by A000142.at n=45A088412
• Primes p such that p! + 1 is also prime.at n=8A093804
• Least n-gap prime: a(n) = least prime p for which there is no prime between n*p and n*q, where q is the next prime after p.at n=40A195325
• Primes of the form x^3 + y^3 + 1, where x and y are primes.at n=24A214175
• G.f. satisfies: A(x) = Sum_{n>=0} x^n * A(x)^(n^2) * A(-x)^(n^2).at n=12A216969
• Primes whose base-6 representation is a square when read in base 10.at n=28A267820
• For a lesser p of twin primes, let B_(p+2) and B_p be sequences defined as A159559, but with initial terms p+2 and p respectively. The sequence lists p for which all differences B_(p+2)(n)-B_p(n)<=6.at n=43A276848
