Possible improvements for Belyi maps

[jwj61]

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 probably be a knowl

The curve and map should be raw/typeset toggles

The monodromy group is the geometric Galois group of the map. It would be nice to include the generic Galois group this gives over the base field

Agree with all of these suggestions!

[jwj61]

Triangle group is now a knowl (it already existed!)
