Abstract: A graph G=(V,E) with p vertices and q edges is called Lehmer-4 mean graph, if it is possible to label verticesxЄV with distinct label g(x) from 2,4,6,8,.….…... 2p in such a way thatwhen eachedge e=uv islabeledwithg(e=uv)= (or) ,then the edge labels are distinct. In this case,g is called Lehmer-4 meanlabelingof G. Inthis paper, Lehmer-4 mean labeling have been introduced.
