2016-05-12 02:04:38 +0200	asked a question	Convert a symmetric function into a polynomial on elementary symmetric functions The following is a variant of a previous question (32569). What command fills in the blank? `sage: e = SymmetricFunctions(QQ).e() sage: u = e[3](e[2]) sage: u e[3, 3] + e[4, 1, 1] - 2e[4, 2] - e[5, 1] + e[6] sage: R.<e1,e2,e3,e4,e5,e6> = PolynomialRing(QQ, 6) sage: p = _the_blank_() # What command goes here? sage: p e1^2e4 + e3^2 - 2e2e4 - e1*e5 + e6`
