-BIMAGIC GRAPHS
For any abelian group Awritten additively, we denote Let Gbe a graph with vertex set and edge set A mapping is called an edge labeling. Observe that the edge labeling induces a vertex labeling defined by
A graph Gis called an A-magic graph if is a constant for all Let Gbe a graph and let denote its line graph. If a graph Gand its line graph are both A-magic, then we say that Gis an A-bimagic graph. In this paper, we consider the Klein 4-group and investigate graphs which are -bimagic.
