%N Numbers n whose reverse binary representation has the following property: let a 0 mean "halving" and a 1 mean "k > 3k+1". The number describes an operation k > f_n(k). If the equation f_n(k) = k has an integer solution, n is a term in the sequence.
%C Suggested by A125626.
%C Note that f_n(x) is always a linear function of x.
