Ah sorry,
P=graphs.PetersenGraph()
being the P in question if anyone was curious.

Hi, I'm trying to construct an odd graph (http://en.wikipedia.org/wiki/
Odd_graph).
My first thought was to use
X = Set([1,2,3,4,5])
V=(X.subsets(2))
to get the desired subsets for the vertex set. That does get the
subsets, but converting it into a graph doesn't seem to work.
T=Graph(V) gives:

You could try to get the paper through your library or pay for it from
Wiley. Here's the citation and link:

Oh, I forgot to mention, Ubuntu 9.04's pgf is at the latest version
2.0
I think my first message was really unclear. What I meant was, if I
include \usepackage{tikz} at the top of a tex file and render it
manually on the command line, then I don't get the Unknown environment
"tikzpicture" error,
Hi, I was motivated to install Sage from the Graph Theory example on
http://mvngu.wordpress.com/2009/06/24/sage-4-0-2-released/ (the
release tour). To run it I downloaded tkz-berge.sty and tkz-graph.sty,
but I still get the error Unknown environment "tikzpicture" on running
the example.
