%N Primes p such that (p-2)/11 is not a prime number.
%C The old definition was "Start with the list of primes; accept 2 but remove the list of primes S(2); accept the next prime (3) but remove the list of primes S(3); repeat".
%C If p is a prime, S(p) denotes the list of primes {11*p+2, 11(11*p+2)+2, 11(11(11*p+2)+2)+2, ...}, stopping as soon as we reach the first composite number.
