 600-cell - Wikipedia, the free encyclopedia
When interpreted as quaternions, the 120 vertices of the 600-cell form a group under quaternionic multiplication.
The boundary of the 600-cell is composed of 600 tetrahedral cells with 20 meeting at each vertex.
Together they form 1200 triangular faces, 720 edges, and 120 vertices.

The pentagons are sections of dodecahedral cells parallel to a face of such a cell.
The pentagons are again sections of dodecahedral cells parallel to a face of such a cell.

 Encyclopedia: 120 cell
Finding the 120 dodecahedra that make up this figure is a little easier than finding the cells in a 600-cell.
The 24 vertices of the 24-cell plus the 96 Golden Ratio points should give you the 600-cell 4-dim polytope with 120 vertices, which is the 4-dim version of the icosahedron.
To see how this works, it is convenient to view the 24-cell from a perspective in which it has a past octahedron (6 vertices), a present cuboctahedron (12 vertices), and a future octahedron (6 vertices).

 The Stellated 120-Cell
Recall that the stellated 120-cell has two types of intersection points, the 120 vertices where 12 small stellated dodecahedra meet and the 600 "false vertices" which are the vertices of the central 120-cell.
The model constructed here has icosahedral symmetry, so there is a group consisting of 120 orthogonal transformations in R
For the model constructed on this page, we use white balls for the false vertices, green balls for the real vertices, and black balls for the points where, under the projection, the real and false vertices coincide.

 The Ambo-600-Cell
The cells immediately surrounding each dodecahedron combine to form a rhombicosidodecahedron, so the structure can also be seen as 120 intersecting rhombicosidodecahedra.

 Graphics Archive - 120 Cell Soap Bubble by John Sullivan
This image, produced by postdoc John Sullivan of the Geometry Center, represents tessellation of the 3-sphere by 120 regular dodecahedra.
Three dodecahedra meet along each edge, at 120 degree angles, so the projection can be thought of as a cluster of soap bubbles.
This is the first rendering of soap bubbles made from the basic laws of optics for thin films.

 H4-Zome Polychora
The significance of this partition is as follows: Generally, if a cell lies interior to p(S^3), then the pre-image under p consists of two cells, while if a cell lies on the boundary of p(S^3), then the preimage consists of one cell.
This correspondence is strengthened by noticing that R1 and R2 struts have pentagonal symmetry, Y2 struts have trihedral symmetry, and B2 struts have dihedral symmetry.
This observation is one of the keys to determining the required numbers of connector balls and struts.
