Ok. So I have the following implemented in Maple: * generation of vector partitions. * change of basis: between monomial, elementary and power sums. * Hilbert series for the algebra of multisymmetric polynomials. * Computation of the relations between the elementary polynomials (the output is even

Hi Nicolas. Thankyou for the reply. Sorry for my long reply... I should clarify what my ultimate goal is here. I'm working on a PhD. with Amnon Neeman. I'm trying to refine the result in "An application of classical invariant theory to identifiability in nonparametric mixtures" by Elmore, Hall an

I posted this question http://ask.sagemath.org/question/200/multi-symmetric-functions-and-multi-partitions on AskSage and it was suggested I post the question here. This is what I originally asked: "Does sage support manipulating multi-symmetric functions/polynomials and/or multi-partitions? Mult
