LINKS

Table of n, a(n) for n=1..59.

FORMULA

a(n) = A000720(A068231(n))

EXAMPLE

a(1)=5 since the 5th prime, A000040(5)=11, is the first one to be equal to 11 (mod 12).

a(2)=9 since the 9th prime, A000040(9)=23, is the second one to be equal to 11 (mod 12).

PROG

(PARI) for( n=1, 999, prime(n)%12==11 & print1(n", "))

CROSSREFS

A116610 lists the even terms of this sequence, divided by 2.

Sequence in context: A228218 A106503 A267648 * A246156 A059655 A250120
