So, with pdfpages's includepdf one can include several pages of a pdf in the document. But this forces a pagebreak which leaves a lonely and unhappy section title.
\includepdf[nup=2x3, pages={6-}]{present.pdf}
Since internally includepdf uses includegraphics now can do
\fbox{\centering \includegraphics[page=6, scale=0.71]{present.pdf}}
To embed a page on the pdf.
However, how can we embed 2x3 pages?
I'm guessing I could do the includegraphics trick six times, but it's not very elegant. Any suggestions?
