4-6 duoprism
In geometry of 4 dimensions, a 4-6 duoprism, a duoprism and 4-polytope resulting from the Cartesian product of a square and a hexagon. The "4-6 duoprism" cells exist in some of the uniform 5-polytopes in the B5 family. 4-6 duopyramid. The dual of a "4-6 duoprism" is called a 4-6 duopyramid. It has 18 digonal disphenoid cells, 34 isosceles triangular faces, 34 edges, and 10 vertices. <BR>Orthogonal projection Related polytopes. The 2-3 duoantiprism is an alternation of the 4-6 duoprism, represented by , but is not  uniform. It has a highest symmetry construction of order 24, with 22 cells composed of 4 octahedra (as triangular antiprisms) and 18 tetrahedra (6 tetragonal disphenoids and 12 digonal disphenoids). There exists a construction with regular octahedra with an edge length ratio of 1 : 1.155. The vertex figure is an augmented triangular prism, which has a regular-faced variant that is not isogonal. <BR>Vertex figure for the 2-3 duoantiprism
