英文摘要 | A concealed non-Kekulean benzenoid (CNB) is a benzenoid with the same number of starred and unstarred (black and white) vertices but no Kekule structure. The search for CNBs was pursued to h (number of hexagons) = 16 by computer programming. For h = 14, the previously controversial number of 9804 systems was confirmed by a construction method without use of computers. In the Appendix, the previously deduced numbers for concealed non-Kekulean helicenes with h = 11, 12, and 13 by the construction method are verified by new computer enumerations. |
