Appears in sequences

• Primes p such that p, p+2, p+6, p+12 and p+14 are consecutive primes.at n=17A078946
• Primes p such that p+2, p*(p+2)+18 and p*(p+2)+20 are also prime.at n=11A130737
• 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=39A276848
• Number of vertices in a complete bipartite graph where the vertices in the two parts are placed on opposite sides of a parabola at integer y coordinates y = 1, 2, ...n.at n=26A392442
• Prime numbersat n=11511
