Okay, thanks a lot for the quick help again!

Dear Robert,

Thank you for the quick reply. Okay, I will try the OFF export.

Is there a way of doing this for several polytopes at once? The reason for doing this is to do some automated search for polytopes with a given ratio of vertices and faces, as well as a 3-coloring of vertices.

The ...

Is there a way to export the incidence relation between the faces <-> edges and edges <-> vertices of a given polytope in Stella? Alternatively, is there some export option that would it make easy to retrieve this information?

What I had in mind was e.g. for the relations faces <-> edges of the ...
