摘要：

Polycyclic aromatic hydrocarbons with the maximal numbers of Kekule structures for any number h of benzenoid rings are shown to be branched cata-condensed systems. Their structures present regularities with periodicities of three and four in terms of h. An analysis of their structures is presented, and the recurrences are highlighted.
