Query: On the Grundy number of Cameron graphs   The Grundy number of a graph is the maximal number of colors attained by a
first-fit coloring of the graph. The class of Cameron graphs is the Seidel
switching class of cographs. In this paper we show that the Grundy number is
computable in polynomial time for Cameron graphs.
