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.
Vertex coordinates[edit | edit source]
The coordinates of a decagonal-decagrammic duoprism, centered at the origin with unit edge length, are given by:
Representations[edit | edit source]
A decagonal-decagrammic duoprism has the following Coxeter diagrams:
- x10o x10/3o (full symmetry)
- x5x x10/3o () (H2×I2(10) symmetry, decagons as dipentagons)
