Aug 7, 2017 at 12:22 | comment | added | Moritz Firsching | What do you expect as an answer? Recent mentions of polyhedron/polytopes with different meanings? Or just a simple "no"? | |

Feb 9, 2017 at 16:38 | comment | added | Joseph O'Rourke | @Qfwfq: I stand corrected: "polytope" is usually understood to be convex, especially more recently than 1967, when Grünbaum's book was published. | |
Feb 9, 2017 at 16:07 | comment | added | Qfwfq | @Joseph O'Rourke: if a polytope were always convex this book would have a different title: google.it/imgres?imgurl=http://t1.gstatic.com/… | |
Feb 9, 2017 at 12:14 | comment | added | Joseph O'Rourke | It is a shame there is not an International Standards Organization that attempts to normalize mathematical terms :-). In its absence, I think you are correct that the terminology is not standardized. In many contexts, a "polyhedron" is (possibly) nonconvex unless preceded by "convex," whereas "polytope" is always convex. | |
