Bounding prime for the first k-Ramanujan prime. A277718

Smallest prime such that n·k(n)²+n·k(n)+1 is a prime > (n-1)*k(n-1)²+(n-1)*k(n-1)+1 with k(n)>1 or 0 if n=4 as no prime possible. A104995

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. A294615
