• Primes p of a quadruplet (p,p+2,p+6,p+8) such that (p+(p+2)+(p+6)+(p+8))/60 is a prime.at n=17A177032
• a(1) = 2; thereafter, a(n) is the smallest prime not yet used which is compatible with the condition that a(n) is a non-quadratic residue modulo a(k) for the next n indices k = n + 1, n + 2, ..., 2n.at n=29A249797
