\section{Numbering of the vertices}

There is an option that permits the  marking of the \Index{vertices} (with a black circle) and/or numbers them either globally or individually.
\begin{itemize}
  \item \texttt{\Lkeyword{show}=all} marks all the vertices;
  \item \texttt{\Lkeyword{num}=all} numbers all the vertices;
  \item \verb+show=0 1 2 3+ marks the vertices with the index number 0, 1, 2 and 3;
  \item \verb+num=0 1 2 3+ numbers the vertices with the index number 0, 1, 2 and 3.
\end{itemize}
