Hyper-Seeing the Regular Hendeca-choron
The hendecachoron is an abstract 4-dimensional polytope composed of eleven cells in the form of hemi-icosahedra. This paper tries to foster an understanding of this intriguing object of high symmetry by discussing its construction in bottom-up and top down ways and providing visualization by computer graphics models.
