Steve,

Try

<<DiscreteMath`Combinatorica`

?VertexNumber

The graphics is pretty good with the newer Combinatorica but for a little
more control you might want to try the CombinatoricaGraphics package at my
web site below. Among other things it allows a background to be put on
vertex labels and it allows directed branches to have the arrowheads along
the branch instead of at the end.

I'm using the graph functions in Combinatorica. Is there a built-in way to
get vertex labels
displayed when doing ShowGraph? My graphs have up to about 50 vertices at
most. (Obviously the label
display should remain correct after AddEdges, DeleteEdges, AddVertices,
etc.) I don't see any vertex
labeling option for this function.
	Thanks for any information.
