Enneagrammic-decagrammic duoprism

The enneagrammic-decagrammic duoprism, also known as stestadedip or the 9/2-10/3 duoprism, is a uniform duoprism that consists of 10 enneagrammic prisms and 9 decagrammic prisms, with 2 of each at each vertex.

The name can also refer to the great enneagrammic-decagrammic duoprism.

Coordinates
The vertex coordinates of an enneagrammic-decagrammic duoprism, centered at the origin and with edge length 2sin(2π/9), are given by: where j, k = 2, 4, 8.
