http://ngthanhtrung23.github.io/ACM_Notebook_new/Graph/DirectedMST.h.html WebThe number t(G) of spanning trees of a connected graph is a well-studied invariant.. In specific graphs. In some cases, it is easy to calculate t(G) directly: . If G is itself a tree, then t(G) = 1.; When G is the cycle graph C n with n vertices, then t(G) = n.; For a complete graph with n vertices, Cayley's formula gives the number of spanning trees as n n − 2.
