Did you know that you can embed PDF documents directly inside your
Regina data files?
This means that you can annotate your data with diagrams:

\bigskip

\centerline{
    \includegraphics[scale=0.35]{fig1}\qquad\qquad
    \includegraphics[scale=0.7]{fig2}}

\medskip

\noindent
and also with equations:

\[ \ldots
    \longrightarrow H_n(A \cap B)
    \stackrel{\Phi}{\longrightarrow} H_n(A) \oplus H_n(B)
    \stackrel{\Psi}{\longrightarrow} H_n(X)
    \stackrel{\partial}{\longrightarrow} H_{n-1}(A \cap B)
    \longrightarrow \ldots
\]

The iPad version of Regina allows you to \emph{view} embedded PDF documents,
but not create them.
If you wish to embed new PDF documents inside your data files,
please download a desktop version of Regina from
\texttt{regina-normal.github.io}.
