Sigh, I've implemented this for faces of polyhedral convex cones as well: https://gitweb.michael.orlitzky.com/?p=sage.d.git;a=blob;f=mjo/cone/faces.py It would be a lot nicer to share a single implementation, but if it looked easy to do, I would already have done it. |

This naive proposal seems to fail. There is some re-numbering happening between two polar polytopes. |
