**On the chromatic number of a random 5-regular graphy**

It is widely known that for d 2 a random d-regular graph is a.a.s. not bipartite, and thus has chromatic number at least 3. (We say an event holds asymptotically almost surely... The Chromatic Number of a Graph In this video, we continue a discussion we had started in a previous lecture on the chromatic number of a graph. We define the chromatic number of a graph, calculate it for a given graph, and ask questions about finding the chromatic number of a graph.

A seven-coloring of the plane, and a four-chromatic unit distance graph in the plane (the Moser spindle), providing that the chromatic number of a plane is bounded above by 7 and below by 4. The Golomb graph , Solomon W. Golomb 's ten-vertex four-chromatic unit distance graph... The chromatic number of a graph G, denoted by ? (G), is the minimum number of colours required to colour the vertex set of G so that no two adjacent vertices are assigned the same colour. That is, the vertices of a given colour form a stable set .
