Pajek network converted to sparse adjacency matrix for inclusion in UF sparse 
matrix collection, Tim Davis.  For Pajek datasets, See V. Batagelj & A. Mrvar,                                
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.
