What values of n is Kn in Hamilitionian?
The complete graph ( K_n ) is Hamiltonian for all ( n \geq 3 ). This means that a Hamiltonian cycle exists in ( K_n ) for any number of vertices ( n ) greater than or equal to 3. For ( n = 1 ) and ( n = 2 ), ( K_n ) does not contain a Hamiltonian cycle, as there aren’t enough vertices to form a closed loop. Thus, ( K_n ) is Hamiltonian for ( n \in {3, 4, 5, \ldots} ).
What is the automorphism group of a complete bipartite graph?
The automorphism group of a complete bipartite graph K_n,n is (S_n x S_n) semidirect Z_2.
What makes a complete graph?
A complete graph is a type of graph in which every pair of distinct vertices is connected by a unique edge. In a complete graph with ( n ) vertices, denoted as ( K_n ), there are exactly ( \frac{n(n-1)}{2} ) edges. This means that every vertex is adjacent to every other vertex, resulting in a highly interconnected structure. Complete graphs are often used in graph theory to illustrate maximum connectivity among a set of points.
What is the automorphism group of a complete graph?
The automorphism group of a complete graph ( K_n ) (where ( n ) is the number of vertices) is the symmetric group ( S_n ). This is because any permutation of the vertices of ( K_n ) results in an isomorphic graph, as all vertices are equivalent in a complete graph. Therefore, the automorphism group consists of all possible ways to rearrange the vertices, corresponding to the ( n! ) permutations of the ( n ) vertices.
How many Hamiltonian circuits not counting reversals are there in a complete graph with 7 vertices?
In a complete graph with ( n ) vertices, the number of distinct Hamiltonian circuits, not counting reversals, is given by ( \frac{(n-1)!}{2} ). For a complete graph with 7 vertices, this calculation is ( \frac{(7-1)!}{2} = \frac{6!}{2} = \frac{720}{2} = 360 ). Therefore, there are 360 distinct Hamiltonian circuits in a complete graph with 7 vertices when not considering reversals.
Is the complete graph on 5 vertices planar?
No, the complete graph of 5 vertices is non planar. because we cant make any such complete graph which draw without cross over the edges . if there exist any crossing with respect to edges then the graph is non planar.Note:- a graph which contain minimum one edge from one vertex to another is called as complete graph...

What is the complexity of solving the k-color problem on a given graph?
The complexity of solving the k-color problem on a given graph is NP-complete.
Is determining the minimum spanning tree of a graph an NP-complete problem?
Determining the minimum spanning tree of a graph is not an NP-complete problem. It can be solved in polynomial time using algorithms like Prim's or Kruskal's algorithm.
