New Concept of Finite Group (Zp^n q) on the Sum Graph with Some Topological Indices

In this paper, we study the extended graph theory in the sum group via Zpnq which is Zpnqby two distinct orders, the sum is greatest than the order of the group Zpnq where p,q are prime numbers. We have some results that the group sum graph of Zpnqare connected, cyclic, etc., if they satisfy some properties of the graph theory and compute all the degrees of graphs. Furthermore, we shall calculate the famous topological indices via generalized it.
