you can download:

both units). The time was then almost trivial. Suppose I

Hi,
It seems to me that the show method for DiGraphs is not working
correctly in Sage 3.4.
EXAMPLE:
sage: G = DiGraph({1:{2: 1}, 2:{1:1}})
sage: G.show()
sage: DiGraph(G.laplacian_matrix()).show()
1. The first call to show draws the graph with an edge missing.
2. The second call produces edges
Lucio,
Thanks for the reply.
Downloaded the iso and burned a new CD. Tested it on same 2 machines,
plus one more:
6-month old Toshiba laptop, with admittedly screwy wireless hardware
(twice)
Older Dell desktop, wired networking (twice)
2-month old home-built desktop, wired networking (once)

I'm afraid I don't have anything to offer for multidimensional

Yes, there should be. It's a weighted graph with loops on the vertices,
since the laplacian has nonzero diagonal entries.
Thanks,

The diagonal entries in the laplacian give the out_degrees of the
