%N A046120 Largest member of a sexy prime triple; value of p+12 where (p,p+6,p+12) 
               are all prime but p+18 is not
%C A046120 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 
               largest member, e.g. a(4)=59 is the largest member of the sexy prime 
               triple (47, 53, 59), but is the fourth member of the sexy prime quadruple 
               (41, 47, 53, 59). [From Daniel Forgues (squid(AT)zensearch.com),
