See A091924 for the sequence whose definition works "the other way round": Actually, the base-11 representation of the terms of this sequence here. - M. F. Hasler, Jan 03 2014

EXAMPLE
The prime p = 31 is written 29 in base 11, and 29 read in base 10 is again a prime. So 31 is a term.
MATHEMATICA
b11pQ[n_]:=Module[{d=IntegerDigits[n, 11]}, Max[d]<10&&PrimeQ[FromDigits[ d]]]; Select[Prime[Range[400]], b11pQ] (* Harvey P. Dale, Apr 17 2018 *)
PROG
(PARI) is(p, b=10, c=11)=vecmax(d=digits(p, c))<b&&isprime(vector(#d, i, b^(#d-i))*d~)&&isprime(p) \\ M. F. Hasler, Jan 05 2014
