%N Numbers n with unique occurrence of all binary substrings representing primes in binary representation of n.

%C A078826(a(n)) = A078827(a(n)); A078830 is a subsequence.

%e n=12 -> '1100' contains two substrings representing distinct primes: '10'=2 and '11'=3, therefore 12 is a term.

%Y Cf. A078826, A078827, A078830, A007088.
