A hierarchical taxonomic system for the nuanced description (both as nouns and adjectival forms) of the configurations has been presented and is briefly described here. The highest taxonomic rank is the class (adj: classic) which, for this type of stereoisomerism, is ABn (Fig. ). Below class is family (adj: familial), for example, AB4 (Fig. ) followed by genus (adj: generic) such as "regular tetrahedral" for which we use the nomenclatural configuration symbol T-4 (Fig. ). At the lowest taxonomic rank is species (adj: specific) where the B-atoms (or equivalently B-atom unit-vectors) are assigned specific distinct indices. The example in Figure This taxonomy finds wider use when describing other aspects of chemical structure and configuration within the Polytope Formalism.
