The Balaban (3,10)-cage was the first known example of a 10-cage (Balaban 1973; Pisanski 2001). Embeddings of all three possible (3,10)-cages (the others being the Harries graph and Harries-Wong graph) are given by Pisanski et al. (2001). Several embeddings are illustrated below, with the three rightmost being given by Pisanski and Randić (2000) +It is a Hamiltonian graph and has Hamiltonian cycles. It has 1003 distinct LCF notations, with four of length two (illustrated above) and 999 of length 1. +\href{http://mathworld.wolfram.com/topics/GraphTheory.html}% + {\textcolor{blue}{MathWorld}} by \href{http://en.wikipedia.org/wiki/Eric_W._Weisstein}% + {\textcolor{blue}{E.Weisstein}} +} +\end{NewMacroBox} + +\subsection{\tkzname{Balaban graph : first form}} +\begin{center} +\begin{tkzexample}[vbox] + \begin{tikzpicture}[scale=.6] + \GraphInit[vstyle=Art] + \SetGraphArtColor{red}{olive} + \grBalaban[form=1,RA=7,RB=3,RC=3] + \end{tikzpicture} +\end{tkzexample} + +\end{center} + + +\vfill\newpage +\subsection{\tkzname{Balaban graph : second form}} +\begin{center} +\begin{tkzexample}[vbox] + \begin{tikzpicture} + \GraphInit[vstyle=Art] + \SetGraphArtColor{gray}{blue!50} + \grBalaban[form=2,RA=7,RB=7,RC=4,RD=2.5] + \end{tikzpicture} +\end{tkzexample} + +\end{center} + +\vfill\newpage +\subsection{\tkzname{Balaban graph : third form} } +\begin{center} + \begin{tkzexample}[vbox] + \begin{tikzpicture} + \GraphInit[vstyle=Art] + \SetGraphArtColor{brown}{orange} + \grBalaban[form=3,RA=7,RB=6.5,RC=5.6,RD=5.6,RE=4.6] + \end{tikzpicture} + \end{tkzexample} + +\end{center} + + +\vfill\newpage + +\subsection{\tkzname{Balaban graph : Balaban 11-Cage}} + + +The Balaban 11-cage is the unique 11-cage graph, discovered by Balaban (1973) and proven unique by McKay and Myrvold (2003).
