THE HARMONIC INDEX AND THE GUTMAN INDEX OF COPRIME GRAPH OF INTEGER GROUP MODULO WITH ORDER OF PRIME POWER

In the field of mathematics, there are many branches study, especially in graph theory, mathematically a is pair sets, which consists non-empty set whose members called vertices and distinct unordered pairs edges. One example from group coprime graph, where defined as two with different x y neighbors if only (|x|,|y|)=1. this author discusses Harmonic Index Gutman Coprime Graph Integer Group Modulo n. The method used research literature review analysis based on patterns formed several case studies for value results obtained study integers modulo n has harmonic index prime natural number.
