The **octagonally tetrablended quasitruncated tesseract** or **otbaquitit** is a nonconvex scaliform polychoron that consists of 64 regular tetrahedra and 16 blends of 2 quasitruncated cubes. 2 tetrahedra and 4 blends of 2 quasitruncated cubes join at each vertex.

It can be constructed as a blend of 4 quasitruncated tesseracts in the same way ondip is constructed as a blend of 4 sidpith. Its vertex figure is in turn a blend of two vertex figures of the quasitruncated tesseract. It has the same symmetry as the octagonal duoprism.
