The octagonal-truncated tetrahedral duoprism or otut is a convex uniform duoprism that consists of 8 truncated tetrahedral prisms, 4 hexagonal-octagonal duoprisms, and 4 triangular-octagonal duoprisms. Each vertex joins 2 truncated tetrahedral prisms, 1 triangular-octagonal duoprism, and 2 hexagonal-octagonal duoprisms.
Vertex coordinates[edit | edit source]
The vertices of an octagonal-truncated tetrahedral duoprism of edge length 1 are given by all permutations and even sign changes of the last three coordinates of:
