Go trough the list of these polytopes, maybe one of these fits your purpose. The omnitruncated one is the "most truncated version" of all of these, so Yes, you can "untruncate" it in some sense. | |

May 19, 2020 at 16:49 | comment | added | F. C. | For the next permutohedron, the squares are no longer facets, so one cannot just remove the squares by removing the associated inequalities defining the polytope, as was the case in dimension 3. | |
