Dishexadecateron

The dishexadecateron or dah is a uniform polyteron composed of 16 pentachora and 16 rectified pentachora. 5 petachora and 10 rectified pentachora form its [[Facetorectified pentachoric]] vertex figure; its facial structure is identical to that of the demipenteract, as their vertex figures fall into the same regiment.

Vertex coordinates
The vertex coordinates of a hexadecapenteract are given by all even sign changes of:
