\begin{center}
\begin{minipage}[!ht]{1cm}
\begin{bundle}{\gpbox{L}}\chunk{\begin{bundle}{\gpbox{L}}\chunk{\begin{bundle}{\gpbox{L}}\chunk{\begin{bundle}{\gpbox{P}}\chunk{\gpbox{2}}\chunk{\gpbox{1}}\end{bundle}}\end{bundle}}\end{bundle}}\end{bundle}
\end{minipage}
\end{center}
Obviously there is a huge white space I don't want, so i deleted \begin{center} and \end{center} to see what happens. Then I get screenshot2, which is not an improvement at all.
What is the correct way to print this out? Thanks!
