The hexagonal-decagonal duoprism or hadedip, also known as the 6-10 duoprism, is a uniform duoprism that consists of 6 decagonal prisms and 10 hexagonal prisms, with two of each joining at each vertex.
This polychoron can be alternated into a triangular-pentagonal duoantiprism, although it cannot be made uniform.

Representations[edit | edit source]
A hexagonal-decagonal duoprism has the following Coxeter diagrams:
- x6o x10o () (full symmetry)
- x3x x10o () (A2×I2(10) symmetry, hexagons as ditrigons)
- x5x x6o () (H2×G2 symmetry, decagons as dipentagons)
- x3x x5x () (A2×H2 symmetry, both of the above applied)
- xux xxx10ooo&#xt (I2(10)×A1 axial)
- xux xxx5xxx&#xt (H2×A1 symmetry, dipentagonal axial)
