%N Fewest odd numbers in a primitive cycle of positive integers under iteration by the 3x-k function, where k=A226630(n).

%C A cycle is called primitive if its elements are not a common multiple of the elements of another cycle.

%C The 3x-k function T_k is defined by T_k(x) = x/2 if x is even, (3x-k)/2 if x is odd.
