    Barabasi/NotreDame_www (matrix ID 1510) in the UF Collection.                 
    Nodes represent pages from University of Notre Dame (domain and       
    directed edges represent hyperlinks between them. The data was collected in   
    1999 by Albert, Jeong and Barabasi.

    NOTE: a similar version of this problem already appears in the UF Collection: 
    web-NotreDame       Barabasi/NotreDame_www                                    
                        in SNAP/:       n: 325,729   nz: 1,497,134                
                        in Barabasi/:   n: same      nz:   929,849                
                        The Barabasi/NotreDame_www is an exact copy of            
                        the graph of that name in the Pajek data set.             
                        The SNAP collection has a different version of this       
                        graph, of which SNAP/web-NotreDame is an exact copy.      
                        It is possible that Barabasi's version of the graph is yet
                        a 3rd version of this graph.
