COMMENTS
A cycle is called primitive if its elements are not a common multiple of the elements of another cycle.
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, where GCD(k,6)=1.

CROSSREFS
k = A226684(n). The smallest integer in the T_k cycle associated with a(n) is A226685(n).
