%N Number of primes with n distinct decimal digits, none of which are 0.
%C a(9) is zero because 1+2+...+9=45 which is divisible by 3, making any number with 9 distinct digits also divisible by 3.  _Wei Zhou_, Oct 02 2011
%e a(1) = #{2,3,5,7} = 4.
%e a(2) = #{13,17,19,23,...,97} = 20. Note that the prime 11 is omitted because its decimal digits are not distinct.
%t Length /@ Table[Select[FromDigits /@ Permutations[Range@9, {i}], PrimeQ], {i,9}] (* _Wei Zhou_, Oct 02 2011 *)
%Y Cf. A112371.
