摘要：

A polyhex (benzenoid or coronoid) isomer is characterized by the formula C(n)H(s), which pertains to the corresponding hydrocarbon. The periodic table for benzenoid hydrocarbons is revisited, and the construction of it is simplified. All-benzenoids are treated with respect to their isomers. A periodic table for all-benzenoid hydrocarbons is proposed, and an easy construction of it is described. It involves the process of "super-circumscribing", a new concept. Numerical data are given for a number of isomer classes of benzenoids, all-benzenoids and single coronoids. These data represent a substantial amount of supplements to the previously known numbers of different polyhex isomers.
