\subsubsection{Cycle graph}
\begin{NewMacroBox}{grCycle}{\oarg{local options}\var{order}}

\medskip
\emph{A cycle graph $C_n$ is a graph on $n$ nodes containing a single cycle through all nodes. Cycle graphs can be generated using \tkzcname{grCycle} in   the \tkzname{tkz-berge.sty} package. Special cases include  the triangle graph and  the square graph.}

\subsubsection{Complete graph}
\begin{NewMacroBox}{grComplete}{\oarg{local options}\var{order}}

\medskip
\emph{The more simple definition is "an undirected graph with an edge between every pair of vertices"  or a complete graph  is a simple graph  in which each pair of graph vertices is connected by an edge. The complete graph  with  $n$ graph vertices is denoted $K_n$.  This graph has $\frac{n(n-1)}{2}$ undirected edges.\\
Geometrically, $K_3$ relates to a triangle,$ K_4$ a tetrahedron is the tetrahedral graph  as well as the wheel graph , $K_5$ a pentachoron, etc \dots}

\subsubsection{Circulant graph}
\begin{NewMacroBox}{grCirculant}{\oarg{local options}\var{order}}

\medskip
\emph{The circulant graph  is defined for any order $n$ at least 3, and every subset $L$ of integers which are less than or equal to $n/2$.  A circulant graph is a graph  in which the $i$th graph vertex is adjacent to the ($i+j$)th and ($i-j$)th graph vertices for each $j$ in a list $L$ . The circulant graphs with $L=\{1;\dots;[n/2]\}$  gives the complete graphs  and the circulant graph with $L=\{1\}$  gives the cyclic graphs. The MÃ¶bius ladders are examples of circulant graphs.\\
 In graph theory, a graph  whose adjacency matrix is circulant is called a circulant graph.\\
The circulant graph on  vertices on a list of nodes  is implemented as \tkzcname{grCirculant} in the \tkzname{tkz-berge.sty} package.}

\subsubsection{Ljubljana graph}
From Wikipedia \url{http://en.wikipedia.org/wiki/Ljubljana_graph}

\emph{The Ljubljana graph was first published in 1993 by Brouwer, Dejter and Thomassen.
In 1972, Bouwer was already talking of a 112-vertices edge- but not vertex-transitive cubic graph found by R. M. Foster, but unpublished. Conder, MalniÄ, MaruÅ¡iÄ, Pisanski and PotoÄnik rediscovered this 112-vertices graph in 2002 and named it the Ljubljana graph after the capital of Slovenia. They proved that it was the unique 112-vertices edge- but not vertex-transitive cubic graph and therefore that was the graph found by Foster.}

It can be   represented in LCF notation as  :

\[
\begin{array}{l}
\Big[ 47, -23, -31, 39, 25, -21, -31, -41, 25, 15, 29, -41, -19, 15, -49, 33, 39, -35, -21, 17,\\ -33, 49, 41, 31, -15, -29, 41, 31, -15, -25, 21, 31, -51, -25, 23, 9, -17, 51, 35, -29, 21,\\ -51, -39, 33, -9, -51, 51, -47, -33, 19, 51, -21,29, 21, -31, -39\Big]^2
