A Symmetrohedron Derived From the Great Rhombicuboctahedron, Which Is Also Known as the Truncated Cuboctahedron

This symmetrohedron has the six regular octagons, eight regular hexagons, and twelve squares of its “parent,” the great rhombicuboctahedron. It was modified by using the “morph duals at 50% by tilting to rectify” function, twice. This left the resulting polyhedron with additional faces: 72 trapezoids (24 each, of three types), and 48 scalene triangles. That’s 146 faces in all. I made it using Stella 4d, which you can try for yourself, free, at http://www.software3d.com/Stella.php.

A Symmetrohedron Derived From the Great Rhombicosidodecahedron, Which Is Also Known as the Truncated Icosidodecahedron

This symmetrohedron has the twelve regular decagons, twenty regular hexagons, and thirty squares of its “parent,” the great rhombicosidodecahedron. It was modified by using the “morph duals at 50% by tilting to rectify” function, twice. This left the resulting polyhedron with additional faces: 180 trapezoids (60 each, of three types), and 120 scalene triangles. That’s 362 faces in all.

A Compound of the Pentagonal Hexecontahedron and Its Mirror Image

This is a compound of left- and right-handed versions of the chiral Catalan solid known as the pentagonal hexecontahedron, which is the dual of the snub dodecahedron. I made it using Stella 4d, which you can try for free at http://www.software3d.com/Stella.php.

A Compound of the Pentagonal Icositetrahedron and Its Mirror Image

This is a compound of left- and right-handed versions of the chiral Catalan solid known as the pentagonal icositetrahedron, which is the dual of the snub cube. I made it using Stella 4d, which you can try for free at http://www.software3d.com/Stella.php.

Three Compounds from the Stellation-Series of the Triakis Octahedron

The first solid below is the sixth stellation of the triakis octahedron, one of the Catalan solids. It’s also a compound of three square trapezohedra.

The next solid is the 8th stellation of the triakis octahedron, and it’s also a four-part compound of partial cubes.

Finally, here’s the 18th stellation of the triakis octahedron, which is also a compound of six square-based pyramids.

Two Views of a Wrinkled Octahedron

The image above has faces colored by number of sides, while the one below is in “rainbow color mode.” I made these using Stella 4d, which you may try for free at http://www.software3d.com/Stella.php.

A Compound of Four Hexagonal Prisms

I made this by faceting a great rhombicuboctahedron, using Stella 4d, a program you may try for free at this website: http://www.software3d.com/Stella.php.

A 98-Faced Polyhedron

This polyhedron has fourteen regular faces: six squares, and eight hexagons. Its irregular faces include twelve rhombi, 24 obtuse isosceles triangles, and 48 acute scalene triangles, for a total of 98 faces. It has cuboctahedral symmetry. I made it using Stella 4d, a program you may try for free at http://www.software3d.com/Stella.php. The first image shown here has the faces colored by face type, while the second image shows what it looks like in “rainbow color mode.”

Here’s a third one, with the faces colored by number of sides.
