4D Euclidean space


Polytope of the Month

This month, we introduce an interesting CRF polytope that sports elongated square bi­pyramids (J15) as cells. This is the octa-augmented runcinated tesseract:

The octa-augmented runcinated tesseract

It has 72 vertices, 256 edges, 256 polygons, and 72 cells (including 24 elongated square bipyramids), and is related to the 24-cell as a modified partial Stott expansion, besides being an augmentation of the runcinated tesseract.

So go on over to the octa-augmented runcinated tesseract page to learn more about the structure of this interesting polychoron. As is customary, we provide full Cartesian coordinates.
