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/. ------------------------------------------------------------------------------ Bill Cherowitzo: Graph and Digraph Glossary http://www-math.cudenver.edu/~wcherowi/courses/m4408/glossary.html Pajek's network: Barbara Zemlji"c, 2. nov 2003 The original problem had 3D xyz coordinates, but all values of z were equal to 0, and have been removed. This graph has 2D coordinates.
