An Offspring of a Dodecahedron and a Tetrahedron
To make this polyhedron, I first changed the symmetrytype of a dodecahedron from icosahedral to tetrahedral, then stellated it twice. This was done using Stella 4d, a program you may try for free at http://www.software3d.com/Stella.php.

An Oblique Truncation of the Tetrahedron
This polyhedron has sixteen faces: four equilateral triangles, and a dozen kites. It was created using Stella 4d, which may be found at http://www.software3d.com/Stella.php.

A Hybrid of the Tetrahedron and the Great Dodecahedron
I made this by stellating a dodecahedron repeatedly, but doing so with Stella 4d, the polyhedralmanipulation software I use (available here), set to use tetrahedral symmetry, rather than the higherorder icosahedral symmetry (which I often call “icosidodecahedral” symmetry) inherent to … Continue reading

A Dodecahedron with Four SymetricallyTruncated Vertices
Dodecahedra have icosahedral (also called icosidodecahedral) symmetry. In the figure above, this symmetry is changed to tetrahedral, by truncation of four vertices with positions corresponding to the vertices (or, instead, faces) of a tetrahedron. The interchangeability of vertices and faces … Continue reading
