 ClebschGraph
 construct Clebsch graph

 Calling Sequence ClebschGraph() ClebschGraph(V)

Parameters

 V - set or list of size 16 (optional)

Description

 • The ClebschGraph command creates the Clebsch graph on 16 vertices.
 • The Clebsch graph is a non-planar, triangle-free, and 5-regular graph with chromatic number 4. As an option, you may input the labels of the vertices as a list of size 16.
