muEC::TYP::IseA – tests whether the argument is a product of generators of the e-basis on a formal alphabet expression

The muEC::TYP::IseA function tests whether expr is a product of generators of the e-basis on a formal alphabet expression, that is a product of elementary symmetric functions on a given alphabet.

The indexing vector must be a partition.

The alphabet can be for instance a polynomial in A1, A2, ....

Note that the Ai's are the only formal variables in alphabets.
