Snub hexacosihecatonicosachoron

The snub hecatonicosachoron, omnisnub hecatonicosachoron, omnisnub hexacosichoron, or snahi is a convex isogonal polychoron that consists of 120 snub dodecahedra, 600 snub tetrahedra, 720 pentagonal antiprisms, 1200 triangular antiprisms, and 7200 irregular tetrahedra. Each vertex joins 4 tetrahedra and 1 of each of the other 4 cell types. It can be obtained through the process of alternating the great disprismatohexacosihecatonicosachoron. However, it cannot be made uniform, as it generally as 6 edge lengths, which can be minimzed to no fewer than 3 different sizes.

Using the ratio method, the lowest possible ratio between the longest and shortest edges is 1:a where a is approximately 1.2661327136794291861309032.
