How many sides does a rhombicosidodecahedron?

The prefix "icosidodeca" indicates icosi = 20 do = 2 deca = 10 a 32 sided polyhedron. However, a 32 sided polyhedron should be called a triacontadihedron: (30 + 2) rather than (20 + 12). In my view, the use of Greek prefices is pretentious and is only useful for obfuscation and irritating your readers. I prefer the much simpler "32-hedron with rhombic faces". Clear and easy for anyone to understand.
