| Feb 17, 2014 at 18:30 | comment | added | Kiu | I actually have been interested in very similar (perhaps the same) question some years ago. I think I can give an algebro-geometric (not combinatorial) argument for why the vertices that are not mapped to the vertices of $\phi(P)$ do not appear in the formula, at least for the case of $P =$ a Gelfand-Zetlin polytope. I would be very much interested to know if you have a combinatorial argument in this case. | |

| Jul 10, 2013 at 20:08 | comment | added | Igor Makhlin | Hm... I wouldn't call any of the polytopes I'm working with "small". But maybe I can come up with one, let me see... | |
| Jul 10, 2013 at 19:59 | comment | added | David E Speyer | Could you add a small, nontrivial, example? Thanks! | |
