Popis:	Let F C denote the basic quasi-symmetric functions, in Gessel's notation (1984) ( C any composition). The plethysm s λ oF C is a positive linear combination of functions F D . Under certain conditions, the image under the involution ω of a quasi-symmetric function defined by equalities and inequalities of the variables is obtained by negating the inequalities.
