A112741 Primes p such that zeta(1-2p)/zeta(-1) is prime. 1


%S 13,17,19,37,59,337,2153

%N Primes p such that zeta(1-2p)/zeta(-1) is prime.

%C Found by David Broadhurst in 2002. Note that zeta(-1)=-1/12. Hence zeta(1-2p) has denominator 12 and prime numerator.

%Y Cf. A112548 (n such that the numerator of zeta(1-n) is prime).
