Great disdisantiprismatosnub disprismatosnub dicupolisnub dodecakishecatonicosachoron

The great disdisantiprismatosnub disprismatosnub dicupolisnub dodecakishecatonicosachoron, or giddapsiddip sidducstwy, is a nonconvex scaliform polychoron that consists 120 disrhombidodecahedra, 720 compounds of two pentagonal antiprisms, 720 compounds of two pentagrammic retroprisms, 720 blends of two pentagrammic cupolae, and 7200 compounds of two triangular prisms.

This polychoron can be obtained as the blend of 10 great swirlprismatic hexacositrishecatonicosacupolidishecatonicosachora. In the process some of the pentagrammic cupolae blend on their decagrams, while the other cells compound as noted above.

It was discovered by _Geometer in 2021.
