Definition:Cycle Graph

Definition
A cycle graph is a graph which consists of a single cycle.

The cycle graph of order $n$ is denoted $C_n$.

A cycle graph is $2$-regular.

 * From Characteristics of Eulerian Graph, it is clear that every cycle graph is Eulerian.


 * It is also trivially clear that every cycle graph is Hamiltonian.


 * $C_n$ is bipartite $n$ is even.


 * $\forall n \ge 3: C_n$ is a polygon with $n$ sides.


 * $C_1$ is a loop-graph.


 * $C_2$ is a multigraph.


 * $C_3$ is the complete graph $K_3$.


 * $C_4$ is the complete bipartite graph $K_{2, 2}$.
