I was wondering if there is an implementation of rings over Galois Fields F[x, y ...]? It seems that `SemialgebraicSets` are not supposed to use with custom fields other from R or C. I know about `Nem…

When inputting `4` as field bound, the calculator assumes `Z_4`, which is not a finite field, instead of `GF(4)`, which is.
I would recommend making it explicit that this calculator works with the …

Thanks for posting this. I've spent sometime to see if this could be made to execute any much faster than it it already does. The xor8 and the Galois field look up stuff launches it into hyper drive. …

The knowl for geometry of a Belyi map says that it corresponds to a triangle group Delta(a,b,c).
- the values of a, b, and c for the page we are on are not given
- "triangle group" should probab…

We should probably add a method to the `Field` typeclass to return the characteristic of a field. Among other things, this would let us add a test to make sure that the characteristic is actually pri…

The first step is to add the module which implements the reduction by recyling it from current galois_16.

Sorry if this isn't the right place (ie, do Documentation Issues go here?), but the function flattenRing asserts:
> write a ring as a (quotient) of a polynomial ring over ZZ or a prime field

The GF command seems to set the symbol "a" to some random value of the field created. For example, when I run the following block of code:
`restart`
`a`
`GF(500009);`
`a`
the first line "a" tells…

Right now, `is_abelian()` fails for relative number fields as it calls `is_galois()` which is set to fail for relative number fields.
One can check if it is abelian by looking at `automorphisms()` …

The dependency on [HaskellForMaths](https://hackage.haskell.org/package/HaskellForMaths) turned out to be not a wise choice. Even though it provides an implementation of field extensions (finite fiel…
