This polyhedron combines the faces of an icosidodecahedron (red and blue) with the those of a rhombic triacontahedron (green). The gaps between those two sets of polygons are the yellow rectangles. I made this using the “morph duals by expansion” function of *Stella 4d*: *Polyhedron Navigator.* You can try this program for yourself, free of charge, at http://www.software3d.com/Stella.php.

Is there a name for this polyhedron? I had this in mind but it’s the only example I can find when I searched 30 rhombi, 60 rectangles, 12 pentagons and 20 triangles. I suppose there are infinite variations if you keep the golden rhombi and vary the dimensions of the rectangles.

There’s no name that I know of. The title of the post was my attempt at one.
