%N A226679 Record-breaking values, for increasing k = A226630(n), of the conjectured number of primitive cycles of positive integers under iteration by the Collatz-like 3x-k function.
%C A226679 A cycle is called primitive if its elements are not a common multiple of the elements of another cycle.
%C A226679 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 k is odd.
%C A226679 For primitive cycles, GCD(k,6)=1.
%Y A226679 k = A226680(n).
