For a finite group G with V(G) as the set of all non-central conjugacy classes of it, the conjugacy class graph 􀀀 (G) is defined as: its vertex set is the set V(G) and two distinct vertices aG and bG are connected with an edge if (o(a), o(b)) > 1. In this paper, we determine the tree-number of the conjugacy class graphs of metacyclic groups of order less than thirty.


Metacyclic group, conjugacy class graph, tree-number.
