Cosmochoron (EntityTopic, 12)
From Higher Dimensions Database
- The hypervolumes of a cosmochoron with side length l are given by:
total edge length = 1200l
total surface area = 180√(25 + 10√5) · l2
surcell volume = 30(15 + 7√5) · l3
bulk = Unknown
Here are two perspective projections of the hecatonicosachoron into 3D. The highlighted center cell is closest to the 4D viewpoint. It is surrounded by 12 dodecahedra in a second layer. The right-hand image also shows the third layer of 32 dodecahedra. After this is a fourth layer of 30 dodecahedra lying on the spherical "equator", followed by three more layers mirroring the three layers seen here (not seen here, because they lie on the 4D "back" of the shape).
Note that only the projection is rotating; the 4D shape itself is not.
