• a(n) = 52*n^2 - 1.at n=35A158640
• a(n) is the smallest prime p such that there is a multiplicative subgroup H of Z/pZ, of odd order and of index 2n, such that for any two cosets H1 and H2 of H, H1 + H2 contains all of (Z/pZ)\0, except that H+H contains all of (Z/pZ)\0 except -H. If no such prime exists, a(n) = 0.at n=22A294615
• a(n) is the least prime p such that (p^2 - 6)/5^n is prime.at n=6A358426
