Chamfered tesseract

The chamfered tesseract, also known as the octatruncated icositetrachoron, is a convex polychoron. It has 8 cubes and 24 square bifrustums as cells. It can be obtained as the convex core of a tesseract with hyperplanes passing under each square face. It can also be made by truncating an icositetrachoron at 8 vertices of an inscribed hexadecachoron.

It is the convex core of several uniform polychora: garpit, pinpith, gaqript, pinnatoth.
