| Notes |
------------------------------------------------------------------------------
Pajek network converted to sparse adjacency matrix for inclusion in UF sparse
matrix collection, Tim Davis. For Pajek datasets, See V. Batagelj & A. Mrvar,
http://vlado.fmf.uni-lj.si/pub/networks/data/.
------------------------------------------------------------------------------
Regarding conversion for UF sparse matrix collection: in the original data
every edge appears exactly twice, with the same edge weight. It could be a
multigraph, but it looks more like a graph. The duplicate edges are removed
in this version. You can always add them back in yourself; just look at 2*A.
------------------------------------------------------------------------------
The original problem had 3D xyz coordinates, but all values of z were equal
to 0.5, and have been removed. This graph has 2D coordinates.
