Yes, you are right again! And if I'm thinking it well (which I doubt by now :P), then the 
base 2 seq is the "fundamental" one because the seq in any other base can be seen as a 
subset of the fundamental (i.e., if the number N is in the seq for a base B, then the 
binary representation of N is in the fundamental seq). I would add the base 2 seq instead 
of the base 10 one, or at least I would contribute both of them! The complementary seq 
1,2,3,5,7,11,13,17,19,23,25... could be nice too.
