NumberOfVertices(G) : Grph -> RngIntElt
The number of vertices of the graph G.
NumberOfEdges(G) : Grph -> RngIntElt
The number of edges of the graph G.
The characteristic polynomial (over the integers) of the graph G;
i.e. the characteristic polynomial of the adjacency matrix of G.
The spectrum of the graph G;
i.e. the roots of the characteristic polynomial of G.
The roots are returned as a set of tuples, each containing a
root and its multiplicity.
