Topological indices of nanotubes are numerical descriptors that are derived from graph of chemical compounds.Such indices based on the distances in graph are widely used for establishing relationships between the structure of nanotubes and their physico‐chemical properties.Types of symmetry groups are commonly used in chemistry. Point groups are used for molecules, whereas, for solids, the 230 space groups are used Neither of these types of symmetry groups are suitable for representing unit cells in solids the symmetry of which is in termediate between that of point groups and space...
