In geometry, the bitruncated tesseract (also called a bitruncated 16-cell) is a uniform polychoron.

[edit] Construction

A tesseract is bitruncated by truncating its cells beyond their mid-points, turning the eight cubes into eight truncated octahedra. These still share their square faces, but the hexagonal faces form truncated tetrahedra which share their triangular faces with each other.
