The Lie algebra L and the subset can be provided either from their structure constants or their infinitesimal generator representation. When providing the Lie algebra L with its structure constants denote the elements of the subspaces by using the symbol X, e.g. {X[1], X[4]}.
Depending of the input Normalizer, will return the base which spans the product space either by using the representation provided or the syntax for the subspaces using the symbol X.
