A Radio Mean labeling of a connected graph G is a one to one map f from the vertex set V(G) to the set of natural numbers N such that for two distinct vertices u and v of G, d(u,v)+⌈f(u)+f(v)2⌉≥1+diam(G). The radio mean number of f, rmn(f), is

In this paper we introduce the concept of order difference interval graph ¡ODI (G) of a group G. It is a graph ¡ODI (G) with V (¡ODI (G)) = G and two vertices a and b are adjacent in ¡ODI (G) if and only if o(b) − o(a) ∈ [o(a), o(b)]. Without
