%N Conjectured record-breaking maximal values, for ascending positive integers k, of the minimal elements of the primitive cycles of positive integers under iteration by the Collatz-like 3x-k function.
%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.
%C For primitive cycles, GCD(k,6)=1.
%Y k = A226682(n).
%Y Cf. A226623, A226665.
