Hemitesseractihemioctachoron

The hemitesseractihemioctachoron, or hatho, also known as bowtie duotegum, 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 opposite quadrants of a tesseractihemioctachoron, or as a bowtie duotegum as the central tetrahedra degenerate into squares.

It is a faceting of the hexadecachoron, using all its vertices and a subset of its edges.

Vertex coordinates
Its vertices are the same as those of the hexadecachoron.
