A plane graph is called symmetric if it is invariant under the reflection across some straight line. We prove a result that expresses the number of perfect matchings of a large class of symmetric graphs in terms of the product of the number of matchings of two subgraphs. When the graph is also centr

## Abstract The study of perfectness, via the strong perfect graph conjecture, has given rise to numerous investigations concerning the structure of many particular classes of perfect graphs. In βPerfect Product Graphsβ (__Discrete Mathematics__, Vol. 20, 1977, pp. 177ββ186), G. Ravindra and K. R.

In this paper we give a necessary and sufficient condition for the generalized Cartesian product to be strongly perfect. The special case of the result is the known theorem concerning the Cartesian product of two graphs.
