Considering its cells, i.e. the tets, more as digonal antiprisms, then always 4 build a closed ring within edgewise connection each, 4 of witch thus are swirling around each other.
This polychoron is not only obtained as the vertex alternated hemiation of the tesseract, the later could be re-obtained from this one by the extension of either its even or its odd facets. In fact it happens to be the kernel of any 2 tesseracts of the great icositetrachoron.
Note that hex can be thought of as the external blend of 4 squascs. Further, the overlay of 2 such fully perpendicular decompositions would amount to the degenerate segmentoteron xo4oo ox4oo&#x.
The number of ways to color the hexadecachoron with different colors per cell is 16!/192 = 108 972 864 000. – This is because the color group is the permutation group of 16 elements and has size 16!, while the order of the pure rotational tesseractic group is 192. (The reflectional tesseractic group would have twice as many, i.e. 384 elements.)
When considered as tet antiprism, the analysis of the being used lacing facets shows that the half-height section results in a half-edge sized co.
Being the dual of tes and considering that one's coordinates, it is apparent that this solid is nothing but a hyperball wrt. the norm |x|+|y|+|z|+|w|.
