Give a mathematical formula for the number of undirected labeled graphs with at most n vertices, n1 possible vertex labels, and n2 possible edge labels, in terms of n, n1, and n2.

Given the weighted graph G (weights represent distance) in Figure 8.10, calculate the minimum spanning tree of the graph. Perform the k-Spanning Tree Clustering with k = 3.
