%F A129864 A000959 INTERSECTION A006567. a(n) is n element of A000959 AND a(n) is 
               an element of A000040 AND R(a(n)) = A004086(a(n)) is an element of 
               A000040.
%e A129864 a(9) = 1009 because 1009 is a lucky number A000959(154) and 1009 is an 
               emirp because 1009 is prime and R(1009) = 9001 is prime (but is not 
               lucky).
