The truncated rhombic triacontahedron is a convex polyhedron constructed as a truncation of the rhombic triacontahedron. It can more accurately be called a pentatruncated rhombic triacontahedron because only the order-5 vertices are truncated.
These 12 order-5 vertices can be truncated such that all edges are equal length. The original 30 rhombic faces become non-regular hexagons, and the truncated vertices become regular pentagons.
The Truncated Rhombic Triacontahedron is the dual of the Pentakis Icosidodecahedron,(2v icosa) it may look quite similar to the Truncated Icosahedron but can be identified by the fact that the pentagons sit back to back and the hexagons (which are mirror symmetric not regular) meet in groups of three.
The regular truncated rhombic triacontahedron (all edges are the same length) is produced with a dual morphing ratio of 33.68244%
