- Vertex description: 3.6.3/2.6
- Faces: 12
- Edges: 24
- Vertices: 12
- External facelets: 32
- Dual: Octahemioctacron (infinite)
- Name breakdown:
- Octa-: 8 faces (triangles) lie parallel to those of an
- -hemi-octa-: Hemi = through the centre of model. Octa = faces
(hexagons) parallel to an octahedron, but only half as many (4) because
This model has two hexagons and two triangles meeting at each vertex, and
all faces lie parallel to faces of an octahedron.
It is a faceted cuboctahedron and also shares its
vertices with the Cubohemioctahedron.
The nets for this model were printed from
using a colour printer. Each net creates a tetrahedron. Some care
must be taken, since some edges of these tetrahedra should be glued
with tabs out, and others left unglued with tabs in, for the
outward-glued tabs to slot into.
