For all planar graphs with n(G) ≤ 5, the statement is correct. Inductive step. Let G have more than 5 vertices. Select a vertex v of degree ≤ 5. It always exists, since else, the number of edges in the graph would exceed the upper bound of 3p−6. By induction, graph G−v is 5-colorable. Consider a 5-coloring of G − v.

WebEuler Path. An Euler path is a path that uses every edge in a graph with no repeats. Being a path, it does not have to return to the starting vertex. Example. In the graph shown below, there are several Euler paths. One such path is CABDCB. The path is shown in arrows to the right, with the order of edges numbered.
