Decagonal-decagrammic duoprism

The decagonal-decagrammic duoprism or distadedip, also known as the 10-10/3 duoprism, is a uniform duoprism that consists of 10 decagonal prisms and 10 decagrammic prisms, with 2 of each at each vertex.

This polychoron can be alternated into the great duoantiprism, which can be made uniform.

Coordinates
The coordinates of a decagonal-decagrammic duoprism, centered at the origin with unit edge length, are given by:
