%N Primes whose base-17 expansion is a (valid) decimal expansion of a prime.
%C See A235126 for the corresponding primes whose base-10 representation is the base-17 representation of the terms here. - _M. F. Hasler_, Jan 05 2014

%e The prime p = 37 is written 23 in base 17, and 23 is again a prime (when interpreted in base 10). Therefore p = 37 is a term of this sequence.
%o (PARI) is_A090713(p)=vecmax(d=digits(p,17))<10&&isprime(vector(#d,i,10^(#d-i))*d~)&&isprime(p) \\ - _M. F. Hasler_, Jan 05 2014
