. The polynomials are expressed in the basis of monomials. muEC::SP::TableYY – table of all double Schubert polynomials
The muEC::SP::TableYY function returns the table of all double Schubert polynomials indexed by codes of permutations in . The polynomials are expressed in the basis of monomials.
When called with the second argument perm, the second alphabet (the yi's) is specialized as the permutation perm of the first one (the xi's): in other words, y.i is sent to x.perm[i].
