Abstract
Let be a group. \textit{The permutability graph of cyclic subgroups of }, denoted by , is a graph with all the proper cyclic subgroups of as its vertices and two distinct vertices in are adjacent if and only if the corresponding subgroups permute in . In this paper, we classify the finite groups whose permutability graph of cyclic subgroups belongs to one of the following: bipartite, tree, star graph, triangle-free, complete bipartite, , , , -free, unicyclic. We classify abelian groups whose permutability graph of cyclic subgroups are planar. Also we investigate the connectedness, diameter, girth, totally disconnectedness, completeness and regularity of these graphs.
