Abstract
In this note we prove a new characterization of the derangement sets of Ferrers graphs and present a bijection between the derangement sets and F_{lambda }-Callan sequences. In particular, this connection reveals that the boolean numbers of the complete bipartite graphs are the D-relatives of poly-Bernoulli numbers.
