 OFFSET 1,1 LINKS Freimut Marschner, Table of n, a(n) for n = 1..63 FORMULA a(n) = prime((n^2 + prime(n)^2)) = prime(A106587(n)). EXAMPLE n = 1, prime(1^2+prime(1)^2) = prime(1 + 2^2) = prime(5) = 11. n = 2, prime(2^2+prime(2)^2) = prime(4 + 3^2) = prime(13) = 41. CROSSREFS Cf. A000290 (squares n^2), A000040 (prime(n)), A001248 (prime(n)^2), A106587 (n^2 + prime(n)^2). Also A011757 is prime(n^2), A096327 is prime(prime(n)^2).
