A topological index, also known as connectivity index, is a molecular structure descriptor calculated from a molecular graph of a chemical compound which characterizes its topology. Various topological indices are categorized based on their degree, distance, and spectrum. In this study, we calculated and analyzed the degree-based topological indices such as first general Zagreb index , geometric arithmetic index , harmonic index , general version of harmonic index , sum connectivity index , general sum connectivity index , forgotten topological index , and many more for the Robertson apex graph. Additionally, we calculated the newly developed topological indices such as the and Sanskruti index for the Robertson apex graph G.
