%N A046118 Smallest member of a sexy prime triple: value of p where (p,p+6,p+12) 
               are all prime but p+18 is not (although p-6 might be.)
%C A046118 p-6 will be prime if the prime triple contains the last 3 primes of a 
               sexy prime quadruple.
%C A046118 If a sexy prime triple happens to include the last 3 members of a sexy 
               prime quadruple this sequence will contain the sexy prime triple's 
               smallest member, e.g. a(4)=47 is the smallest member of the sexy 
               prime triple (47, 53, 59), but is also the second member of the sexy 
               prime quadruple (41, 47, 53, 59). [From Daniel Forgues (squid(AT)zensearch.com),
