%N A065810 Sorted positions of the elements of the quasicyclic group Z+(2a+1)/(2^b) 
               [a > 0 and a < 2^(b-1), b > 0] at the ]0,1[ side of the Stern Brocot 
               Tree (A007305/A007306).
%C A065810 It is easily proved that in the denominators given by A007306, the even 
               values occur only at every third position, but can one find a simple 
               rule for these positions of the denominators which are the powers 
               of 2 only?
