%N A puzzle called "The hidden prime".
%C The first six terms are all emirps. - _Arkadiusz Wesolowski_, Mar 09 2011
%C _Carlos Rivera_ asks for a 6-digit number (prime?) that follows from the first six numbers. No solution has been posted after several years. - _T. D. Noe_, Mar 09 2011
%C The sequence is a cycle of emirps with the middle two digits of each term the same as the second and next-to-last digits of the subsequent term. The first six terms are as given, the seventh term is the unique six-digit extension. - _J. D. Lavelle_, Jul 01 2018
