- Description
- The number of perfect matchings in a benzenoid system increases when its size grows. This raises a question on the lower bound of the number of perfect matchings in benzenoid systems. In this paper, we show that this lower bound is 9. Further- more, we construct an infinite family of benzenoid system whose number of perfect matchings reaches the lower bound.
