 WellsGraph
 construct Wells graph

 Calling Sequence WellsGraph()

Description

 • The WellsGraph command creates the Wells graph.
 • The Wells graph is a 22-regular graph with 32 vertices and 80 edges.

Examples

 > $\mathrm{with}\left(\mathrm{GraphTheory}\right):$
 > $\mathrm{with}\left(\mathrm{SpecialGraphs}\right):$
 > $\mathrm{WG}≔\mathrm{WellsGraph}\left(\right)$
 ${\mathrm{WG}}{≔}{\mathrm{Graph 1: an undirected unweighted graph with 32 vertices and 80 edge\left(s\right)}}$ (1)
 > $\mathrm{IsRegular}\left(\mathrm{WG}\right)$
 ${\mathrm{true}}$ (2)
 > $\mathrm{ChromaticNumber}\left(\mathrm{WG}\right)$
 ${4}$ (3)
