# Five Pictures of the Petersen Graph

Five pictures of the ubiquitous Petersen graph are
shown below. The Petersen graph has cycles of four
different lengths: 5, 6, 8, and 9. Each of the first
four pictures uses one of these cycle lengths for
the outer boundary.

To see an animation that shows the isomorphism
between the first two pictures, click

An SVG picture of a rotating Petersen graph can
be seen here. You will
need an SVG-enabled browser. Firefox and Safari
do not currently (October 2008) support animation
tags.
