It has 122 faces: 20 triangles, 60 squares, 12 pentagons, and 30 rhombs. The 120 vertices exist at two sets of 60, with a slightly different distance from its center. It can also be constructed as a rectified rhombicosidodecahedron. == Other names == * Expanded rhombic triacontahedron * Rectified rhombicosidodecahedron * Rectified small rhombicosidodecahedron * Rhombirhombicosidodecahedron 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Expanded icosidodecahedron」の詳細全文を読む スポンサード リンク
