Heptagrammic-decagrammic duoprism

The heptagrammic-decagrammic duoprism, also known as shestadedip or the 7/2-10/3 duoprism, is a uniform duoprism that consists of 10 heptagrammic prisms and 7 decagrammic prisms, with 2 of each at each vertex.

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

Vertex coordinates
The coordinates of a heptagrammic-decagrammic duoprism, centered at the origin and with edge length 2sin(2π/7), are given by: where j = 2, 4, 6.
