Unfortunately, p.show computes the graph internally and just outputs the figure output. Put, we can do it from scratch:
sage: p = Permutation([3,1,2])
sage: edges = list(enumerate(p,start=1))
sage: d = DiGraph(edges, format='list_of_edges', loops=True)
sage: d
Looped digraph on 3 vertices
sage: latex(d) # prints the latexoutput in the default tikz
sage: view(d) # opens the pdf in a viewer
There is another way to use graphviz + dot2tex, but I always forget how to do it. Personnaly, I like to use the TikzPicture class from my package which uses graphviz the place the nodes + dot2tex to constructs the tikzpicture:
sage: from slabbe import TikzPicture
sage: tikz = TikzPicture.from_graph(d)
sage: print(tikz)

\end{document}
sage: tikz.pdf() # opens up a viewer
sage: tikz.pdf('filename.pdf') # saves the pdf file
To install those optional packages, you do:
sage -i dot2tex
sage -pip install slabbe
At some point, I might move the TikzPicture code from my package to sage. Is this something you would like for instance?
