Special Graphs Complete Graphs A complete graph on n vertices, denoted by K n, is a simple graph that contains exactly one edge between each pair of distinct vertices. Has n(n 1) 2 edges. Cycles A cycleC Nov 11, 2015 · Viewed 2k times. 1. If you could explain the answer simply It'd help me out as I'm new to this subject. For which values of n is the complete graph Kn bipartite? For which values of n is Cn (a cycle of length n) bipartite? Is it right to assume that the values of n in Kn will have to be even since no odd cycles can exist in a bipartite? I can see why you would think that. For n=5 (say a,b,c,d,e) there are in fact n! unique permutations of those letters. However, the number of cycles of a graph is different from the number of permutations in a string, because of duplicates -- there are many different permutations that generate the same identical cycle.Aug 9, 2022 · This video explains how to determine the values of m and n for which a complete bipartite graph has an Euler path or an Euler circuit.mathispower4u.com

"K$_n$ is a complete graph if each vertex is connected to every other vertex by one edge. Therefore if n is even, it has n-1 edges (an odd number) connecting it to other edges. Therefore it can't be Eulerian..." which comes from this answer on Yahoo.com. In graph theory, a regular graph is a graph where each vertex has the same number of neighbors; i.e. every vertex has the same degree or valency.
