In the 4-dimension Euclid space, $A=\{conv(P\cup Q)|P, Q \text{ are zonotopes}\}$, (all points and segments are zonotopes as well, thus all points, segment, trianges and tetrahedrons are in $A$). Let $B=\{\text{any finite Minkowski sum of elements in$A$}\}$. The question is that, for a 4-dimen...

I will point out that the tag (geometry) is deprecated on MO, see the tag-info. Possibly some other geometry-related tag could be used here. (But I'll leave the choice of tags to more experienced users.) — Martin Sleziak 1 min ago
