Editing Cycle graph (section)

==Terminology==
There are many [[synonym]]s for "cycle graph". These include '''simple cycle graph''' and '''cyclic graph''', although the latter term is less often used, because it can also refer to graphs which are merely not [[directed acyclic graph|acyclic]]. Among graph theorists, '''cycle''', '''polygon''', or '''''n''-gon''' are also often used. The term '''''n''-cycle''' is sometimes used in other settings.<ref>{{cite journal |title=Problem 11707 |journal=Amer. Math.

A cycle with an even number of vertices is called an '''even cycle'''; a cycle with an odd number of vertices is called an '''odd cycle'''.
