Counting set covers and split graphs
Journal of integer sequences, Tome 3 (2000) no. 2
Zbl   EuDML
A bijection between split graphs and minimal covers of a set by subsets is presented. As the enumeration problem for such minimal covers has been solved, this implies that split graphs can also be enumerated.
