R: GcdDomain

V: OrderedSet

P: RecursivePolynomialCategory(R, E, V)

The category of square-free regular triangular sets. A regular triangular set `ts`

is square-free if the `gcd`

of any polynomial `p`

in `ts`

and `differentiate(p, mvar(p))`

`w`

.`r`

.`t`

. collectUnder(`ts`

, mvar(`p`

)) has degree zero `w`

.`r`

.`t`

. `mvar(p)`

. Thus any square-free regular set defines a tower of square-free simple extensions.
