This package uses an explicit description of the Groebner basis of the ideal of obvious relations in this algebra based on:

Grayson, Stillmann - Computations in the intersection theory of flag varieties, preprint, 2009

Sturmfels - Algorithms in Invariant Theory, Springer Verlag, Vienna, 1993

- Functions and commands
- buildSymmetricGB -- Groebner basis of elementary symmetric polynomials algebra
- elementarySymmetric -- expression in terms of elementary symmetric polynomials
