In geometry, the metabidiminished rhombicosidodecahedron is one of the Johnson solids (J_81). It can be constructed as a rhombicosidodecahedron with two non-opposing pentagonal cupolae (J_5) removed. Related Johnson solids are: The diminished rhombicosidodecahedron (J_76) where one cupola is removed, The parabidiminished rhombicosidodecahedron (J_80) where two opposing cupolae are removed, The gyrate bidiminished rhombicosidodecahedron (J_82) where two non-opposing cupolae are removed and a third is rotated 36 degrees, And the tridiminished rhombicosidodecahedron (J_83) where three cupolae are removed.
