With Mathematica 6, I can change the default style (medium black disk) for rendering the vertices of a Combinatorica Graph like this: Needs["Combinatorica`"] g = Cycle[3]; ShowGraph[g, VertexStyle -> Disk[Large], VertexColor -> Red] But how can I, for example, change the vertex style so it is, say, a large yellow disk with a thick red boundary? Or even just change it to be a circle? I tried "obvious" things like the following, but they cause errors: ShowGraph[g, VertexStyle -> Graphics[Circle[], ImageSize -> 20]] -- Murray Eisenberg murray at math.umass.edu Mathematics & Statistics Dept.
