The hexagonal-truncated tetrahedral duoprism or hatut is a convex uniform duoprism that consists of 6 truncated tetrahedral prisms, 4 hexagonal duoprisms, and 4 triangular-hexagonal duoprisms. Each vertex joins 2 truncated tetrahedral prisms, 1 triangular-hexagonal duoprism, and 2 hexagonal duoprisms.
Vertex coordinates[edit | edit source]
The vertices of a hexagonal-truncated tetrahedral duoprism of edge length 1 are given by all permutations and even sign changes of the last three coordinates of:
- ,
- .
Representations[edit | edit source]
A hexagonal-truncated tetrahedral duoprism has the following Coxeter diagrams:
- x6o x3x3o () (full symmetry)
- x3x x3x3o () (hexagons as ditrigons)
