 OFFSET 1,1 LINKS K. D. Bajpai, Table of n, a(n) for n = 1..1000 EXAMPLE 1499 is in the sequence because (3^13 mod 13^3) + 1 = 1499 which is prime. 9719 is in the sequence because (3^29 mod 29^3) + 1 = 9719 which is prime. MAPLE KD := proc() local a; a:=3^n mod n^3 + 1; if isprime(a) then RETURN (a); fi; end: seq(KD(), n=1..1000); CROSSREFS Cf. A000040 (prime numbers). Cf. A007519 (primes congruent to 1 mod 8). Sequence in context: A023291 A319329 A058423 * A329775 A226699 A110027 Adjacent sequences: A233903 A233904 A233905 * A233907 A233908 A233909 KEYWORD nonn AUTHOR K. D.
