The sum graph of a finite subset SN is the graph (S,E) with uv∈E if and only if u+v∈S.The sum number of a given graph G is the smallest number of isolated nodes which when added to G result in a sum graph. In this paper we define a new kind of exclusive graph and give the sum number’s maximum and minimum boundary of it.
