The triangular orthobicupola is one of the 92 Johnson solids (J27). It consists of 2+6 triangles and 6 squares. It can be constructed by attaching two triangular cupolas at their hexagonal bases, such that the two triangular bases are in the same orientation.
If the cupolas are joined such that the bases are rotated 60°, the result is the triangular gyrobicupola, better known as the uniform cuboctahedron. Conversely, a triangular orthobicupola can be thought of as a gyrate cuboctahedron, since it is a cuboctahedron with a cupolaic segment rotated.
The triangular orthobicupola is the vertex figure of the gyrated tetrahedral-octahedral honeycomb.
Vertex coordinates[edit | edit source]
A triangular orthobicupola of edge length 1 has vertices given by the following coordinates:

A hexagonal prism can be inserted between the two halves of the triangular orthobicupola to produce the elongated triangular orthobicupola.
