------------------------------------------------------------------------------
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/.                                
------------------------------------------------------------------------------
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.                  

SVD-based statistics:
