%N Conjectured recordbreaking values, for ascending positive integers k, of the maximal element of the primitive cycles of positive integers under iteration by the 3xk function.
%C A cycle is called primitive if its elements are not a common multiple of the elements of another cycle.
%C The 3xk function T_k is defined by T_k(x) = x/2 if x is even, (3xk)/2 if x is odd, where GCD(k,6)=1.
%Y k = A226684(n). The smallest integer in the T_k cycle associated with a(n) is A226685(n).
%Y Cf. A226624, A226667.
