The deltopyramidal pentacosiheptacontahexachoron is a convex isochoric polychoron with 576 kite pyramids as cells.

It can also be constructed as the convex hull of 2 dual icositetrachora and 2 opposite rectified icositetrachora. If the smaller icositetrachoron has edge length 1, the larger icositetrachoron has edge length $11-7{\sqrt {2}}\approx 1.10051$, the smaller rectified icositetrachoron has edge length ${\frac {41-{\sqrt {2}}}{73}}\approx 0.54227$, and the larger rectified icositetrachoron has edge length ${\frac {9{\sqrt {2}}-1}{21}}\approx 0.55847$.
