Tridiminished rhombicosidodecahedron

In geometry, the tridiminished rhombicosidodecahedron is one of the Johnson solids ($J82 – J83 – J84$). It can be constructed as a rhombicosidodecahedron with three pentagonal cupolae removed.

Related Johnson solids are:
 * $C3v$: diminished rhombicosidodecahedron with one cupola removed,
 * $5×6(4.5.10) 3×3+6(3.4.5.4)$: parabidiminished rhombicosidodecahedron with two opposing cupolae removed,
 * $J83$: metabidiminished rhombicosidodecahedron with two non-opposing cupolae removed, and
 * J$82$: Gyrate bidiminished rhombicosidodecahedron with two non-opposing cupolae removed and one cupola rotated 36 degrees.
