Sphenoidal hecatonenneacontadichoron

The sphenoidal hecatonicenneacontadichoron is a convex isochoric polychoron with 192 sphenoids as cells. It can be obtained as the dual of the great rhombated tesseract.

It can also be constructed as the convex hull of a tesseract, a hexadecachoron, and a rectified tesseract. If the tesseract has edge length 1, the hexadecachoron has edge length $$\frac{3+8\sqrt2}{7} ≈ 2.04482$$ and the rectified tesseract has edge length $$\frac{5+9\sqrt2}{41} ≈ 0.77732$$.
