Abstract
:

A graph is asymmetric if its automorphism group is trivial. One measure of the symmetry of a graph ๐บ is the number of its edges need to be "changed'' in order to create an asymmetric graph (or the number of its edges need to be "changed'' to destroy all of its symmetries). We define the asymmetric index of ๐บ, denoted ๐‘Ž๐‘–(๐บ), to be the minimum value ๐‘Ÿ+๐‘  so that adding some set of ๐‘Ÿ edges to ๐บ and deleting some set of ๐‘  edges from ๐บ results in an asymmetric graph. We present some results on asymmetric index, and consider asymmetric index for graphs that are "very'' symmetric.
