| Oct 15, 2015 at 10:44 | comment | added | Tobias Fritz | yes, that's exactly it! | |
| Oct 15, 2015 at 4:54 | comment | added | xzl | Thanks for the answer! Is it because the dual of such polytope can only be a simplex($d$-neighbourly), so the polytope itself is also a simplex? | |
| Oct 14, 2015 at 17:11 | comment | added | Tobias Fritz | This is indeed not possible, since the polar of such a polytope would be $d$-neighbourly: en.wikipedia.org/wiki/Neighborly_polytope | |
