The disnub icosahedron, dasi, or compound of twenty octahedra is a uniform polyhedron compound. It consists of 40+120 triangles. The vertices coincide in pairs, and thus eight triangles join at each vertex.
This compound is a special case of the more general altered disnub icosahedron, with θ = . It has the same edges as the uniform great dirhombicosidodecahedron.
Its quotient prismatic equivalent is the triangular antiprismatic icosayodakoorthowedge, which is 22-dimensional.
