%I A322012 #5 Nov 24 2018 08:15:48 %S A322012 1,2,8,60,1009 %N A322012 Number of s-positive simple labeled graphs with n vertices. %C A322012 A stable partition of a graph is a set partition of the vertices where no edge has both ends in the same block. The chromatic symmetric function is given by X_G = Sum_p m(t(p)) where the sum is over all stable partitions of G, t(p) is the integer partition whose parts are the block-sizes of p, and m is the augmented monomial symmetric function basis (see A321895). A graph is s-positive if, in the expansion of its chromatic symmetric function in terms of Schur functions, all coefficients are nonnegative. %H A322012 Richard P.
