In this paper some further properties of the coefficients of a chromatic generating function introduced by Linial are proved. A combinatorial interpretation of these numbers is given by specializing some results of Stanley on posets to surjective n-colorings of a graph G of order n compatible with l
In this paper, the author develops a general formnla for numbers which are extensions of the Eulerian numbers. A~'n, r) is defined to be the number of n-permutations with r rises of magnitude at least m. Intermediate steps in the derivation include a vertical recurrence ~elation. recurrence relation
