Abstract
A polyhex (system) is a connected geometrical arrangement of congruent regular hexagons so that any two hexagons either share exactly one edge or are disjointed (Balaban 1976; Trinajstić 1992b). A full classification of polyhexes is difficult (Trinajstić 1990; 1992a; Trinajstić, Nikolić et al. 1991; Cyvin BN, Brunvoll and Cyvin 1992b). However, within this broad class of systems the definitions of benzenoids and single coronoids are clear—cut, and various classifications of these systems are well explained. Nevertheless, the terminology in this area is still controversial and subject to discussions (Nikolić et al. 1991; Brunvoll, Cyvin SJ and Cyvin 1991; Trinajstić 1992a).
