V: OrderedSet

P: RecursivePolynomialCategory(R, E, V)

A domain constructor of the category TriangularSetCategory. The only requirement for a list of polynomials to be a member of such a domain is the following: no polynomial is constant and two distinct polynomials have distinct main variables. Such a triangular set may not be auto-reduced or consistent. Triangular sets are stored as sorted lists `w`

.`r`

.`t`

. the main variables of their members but they are displayed in reverse order.
