The decagonal-cuboctahedral duoprism or daco is a convex uniform duoprism that consists of 10 cuboctahedral prisms, 6 square-decagonal duoprisms, and 8 triangular-decagonal duoprisms. Each vertex joins 2 cuboctahedral prisms, 2 triangular-decagonal duoprisms, and 2 square-decagonal duoprisms.
Vertex coordinates[edit | edit source]
The vertices of a decagonal-cuboctahedral duoprism of edge length 1 are given by all permutations of the last three coordinates of:
