(For those who know group theory) An automorphism φ of a simple graph G is a one-one mapping of the vertex-set of G onto itself with the property that φ ( v) and φ ( w) are adjacent whenever v and w are. The automorphism group Γ ( G) of G is the group of automorphisms of G under composition. (i) Prove that the groups Γ ( G) and ...

WebDefinition: A graph is said to be Self Complementary if is isomorphic to its complement, that is . For example, the following graph and its complement are isomorphic as both can be "unravelled" into a path graph: Note that for a graph to isomorphic to another in general, then the number of vertices in both graphs must be the same. http://mathonline.wikidot.com/self-complementary-graphs melissa\\u0027s southern style kitchen
