The power graph P(G) of a group G is the graph whose vertex set is the group
elements and two elements are adjacent if one is a power of the other. In
this paper, we consider some graph theoretical properties of a power graph
P(G) that can be related to its group theoretical properties. As consequences
of our results, simple proofs for some earlier results are presented.
Keywords: power graph, clique number, EPPO-group, maximal cyclic subgroup
