63.34 GlobalParameters

GlobalParameters( gamma )

In a similar way to LocalParameters (see LocalParameters), this function determines the global parameters c_i,a_i,b_i of simple, connected gamma (see BCN89). The nonexistence of a global parameter is denoted by -1.

    gap> gamma := JohnsonGraph(4,2);;
    gap> GlobalParameters( gamma );
    [ [ 0, 0, 4 ], [ 1, 2, 1 ], [ 4, 0, 0 ] ]
    gap> GlobalParameters( BipartiteDouble(gamma) );
    [ [ 0, 0, 4 ], [ 1, 0, 3 ], [ -1, 0, -1 ], [ 4, 0, 0 ] ]
