Let FCdenote the basic quasi-symmetric functions, in Gessel's notation (1984) (C any composition). The plethysm sλoFCis a positive linear combination of functions FD. 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.
