Hemitesseractihemioctachoron

The hemitesseractihemioctachoron, or hatho, is a scaliform polychoron. It has 4 tetrahedra and 4 central bowtie tegums as cells, with 2 tetrahedra and 3 bowtie tegums at each vertex in the form of a bowtie pyramid. It can be obtained by chopping off two quadrants of tho, or as a bowtie duotegum as the central tetrahedra degenerate into squares.

It is a faceting of the hexadecachoron.
