The octagonal-truncated cubic duoprism or otic is a convex uniform duoprism that consists of 8 truncated cubic prisms, 6 octagonal duoprisms, and 8 triangular-octagonal duoprisms. Each vertex joins 2 truncated cubic prisms, 1 triangular-octagonal duoprism, and 2 octagonal duoprisms.
The octagonal-truncated cubic duoprism can be vertex-inscribed into a small rhombated penteract.
Vertex coordinates[edit | edit source]
The vertices of an octagonal-truncated cubic duoprism of edge length 1 are given by all permutations of the last three coordinates of:
