%N "Binary prime squares": a(n) = n^2 written in base 2 and interpreted as a base10 number, if that number is prime; a(n) = 0 otherwise.
%C Another definition: numbers having only digits 1 and 0, which, read in base 10 are primes and in base 2 are perfect squares.
%e a(5)=0 because 5^2 = 25 = 11001_2, and the decimal number 11001 is not prime.
%e a(29)=1101001001 because 29^2 = 841 = 1101001001_2, and the decimal number 1101001001 is prime.
%Y Cf. A108323, A108324, A108325.
