Thanks for taking care of this. I have no experience with categories and what is best practice there. But I think it makes sense to mention my ideas/plans for this module so they can be considered if they need to. Status quo (from my point of view):

Thanks a lot for sharing this valuable perspective. Regarding I think most of the other things are orthogonal to this ticket. |

... of a parent class
CombinatorialPolyhedra
in a new category ofCombinatorialPolyhedralSets
. A parent is defined by (possibly infinite) sets of allowed vertices and facets; every element's set of vertices and facets is a subset of these.Morphisms in the category:
This setup of element/parent/category is parallel to geometric polyhedra:
Polyhedron
/Polyhedra
/PolyhedralSets
.Assigning coordinates in
QQ^3
to labeledvertices
then defines a morphism fromCombinatorialPolyhedra(vertices, facets)
toPolyhedra(QQ, 3)
