 OFFSET 1,1 COMMENTS Primes of this kind (with and without leading zeros) are in A051362 and A034302. Here more terms are given and question is asked: is this sequence finite? From first 1,000,000 primes only 77 are of this kind. LINKS MATHEMATICA The 41st prime is 179, and 17, 19, and 79 are all primes, so 41 is in the sequence. - Harvey P. Dale, Jun 20 2011 CROSSREFS Cf.
