Computation of Neighborhood M‑Polynomial of Octa-Graphene 2D Nanosheet

Carbon-based two-dimensional nanosheets, including the recently discovered Octa-graphene, have emerged as promising materials with diverse applications. To fully understand their properties and potential, it is crucial to explore their topological indices. In this work, we delve into the derivation of the neighborhood M-polynomial for Octa-graphene. This polynomial enables the calculation of neighborhood degree-based topological indices, which are valuable tools for predicting various physical and chemical properties of the material. By employing these indices, we can gain deeper insights into the structure-property relationships of Octa-graphene and other similar nanosheets.
