As the unique smallest cubic graph of girth 8 it is a cage and a Moore graph. It is bipartite, and can be constructed as the Levi graph of the generalized quadrangle. The graph is named after William Thomas Tutte and H. S. M. Coxeter; it was discovered by Tutte (1947) but its connection to geometric configurations was investigated by both authors in a pair of jointly published papers (Tutte 1958; Coxeter 1958a).} -\end{NewMacroBox} - -\subsection{\tkzname{Tutte-Coxeter graph (3,8)-cage or Levi graph}} -An other method to get the same result is~: - -\medskip -\begin{tkzexample}[code only] - \grLCF[RA=7]{-13,-9,7,-7,9,13}{5}\end{tkzexample} - -\bigskip -\begin{center} -\begin{tkzexample}[vbox] -\begin{tikzpicture}[scale=.7] - \GraphInit[vstyle=Art] - \tikzset{VertexStyle/.append style={minimum size=2pt}} - \SetGraphArtColor{blue}{darkgray} - \grTutteCoxeter -\end{tikzpicture} -\end{tkzexample} - -\end{center} - -\endinput
