The tetrakis hexacosichoron, also known as the triangular-pyramidal dischilliatetracosichoron, is a convex isochoric polychoron with 2400 triangular pyramids as cells. It can be obtained as the dual of the truncated hecatonicosachoron.
It can also be obtained as the convex hull of a hecatonicosachoron and a hexacosichoron, where the edges of the hexacosichoron are times the length of those of the hecatonicosachoron. Varying the hexacosichoron's edge length to be anything more than times that of the hecatonicosachoron gives a fully symmetric variant of this polychoron.
