Abstract

The current invariants of all-benzenoids (h, n, m, nu na s - defined in the Introduction), in addition to the number of full and of empty hexagons (v and t), are studied. Their possible values are specified. Some of the relations between these invariants are summarized in a systematic way. The upper and lower bounds for all of them are accounted for as functions of any of these invariants.
