%N A092210 Positive integers n such that the trajectory of n under the Reverse and 
               Add! operation carried out in base 2 (presumably) does not join the 
               trajectory of any m < n.
%C A092210 The conjecture that the base 2 trajectories of the terms do not join 
               is based on the observation that if the trajectories of two integers 
               < 12000 join, this happens after at most 93 steps, while for any 
               two terms listed above the trajectories do not join within 1000 steps. 
               For pairs from 1, 16, 64, 74, 98, 107 this has even been checked 
               for 5000 steps.
%C A092210 Base 2 analogue of A070788 (base 10) and A091675 (base 4).

%e A092210 The trajectory of 2 is part of the trajectory of 1 (cf. A035522); the 
               trajectory of 16 does not join the trajectory of 1 within 10000 steps; 
               the trajectory of 64 does not join the trajectory of 1 or of 16 within 
               10000 steps.
