Abstract: A topological index can be viewed as a conversion of a molecular structure to a real number and it is also known as a parameter to predict important values related to molecular structure. In general, irregularity indices are often used for quantitative analysis of non-regular graph of topological structure. In various applications and challenges in biomedical engineering and chemistry it is important to understand how irregular a molecular structure is? In this paper we determine the reverse irregularity indices of polypropylenimine octamin dendrimers NS1[k], NS2[k] and NS3[k].
