How many edges does a complete graph have.
As defined in this work, a wheel graph W_n of order n, sometimes simply called an n-wheel (Harary 1994, p. 46; Pemmaraju and Skiena 2003, p. 248; Tutte 2005, p. 78), is a graph that contains a cycle of order n-1 and for which every graph vertex in the cycle is connected to one other graph vertex known as the hub. The edges of a wheel which include the hub are called spokes (Skiena 1990, p. 146 ...
It's not true that in a regular graph, the degree is $|V| - 1$. The degree can be 1 (a bunch of isolated edges) or 2 (any cycle) etc. In a complete graph, the degree of each vertex is $|V| - 1$. Your argument is correct, assuming you are dealing with connected simple graphs (no multiple edges.)The sum of the vertex degree values is twice the number of edges, because each of the edges has been counted from both ends. In your case $6$ vertices of degree $4$ mean there are $(6\times 4) / 2 = 12$ edges. Dec 3, 2021 · 1.

Using the graph shown above in Figure 6.4. 4, find the shortest route if the weights on the graph represent distance in miles. Recall the way to find out how many Hamilton circuits this complete graph has. The complete graph above has four vertices, so the number of Hamilton circuits is: (N – 1)! = (4 – 1)! = 3! = 3*2*1 = 6 Hamilton circuits. 17. We can use some group theory to count the number of cycles of the graph Kk K k with n n vertices. First note that the symmetric group Sk S k acts on the complete graph by permuting its vertices. It's clear that you can send any n n -cycle to any other n n -cycle via this action, so we say that Sk S k acts transitively on the n n -cycles.vertex-critical graph G which at the same time is very much not edge-critical, in the sense that the deletion of any single edge does not lower its chromatic number.
