It is the only Catalan solid which does not have a Hamiltonian path among its vertices. ==Lengths and angles== The 60 faces are deltoids or kites. The short and long edges of each kite are in the ratio 6:(7+√5) ≈ 1:1.539344663... The angle between two short edges is 118.22°. The opposite angle, between long edges, is 67.76°. The other two angles, between a short and a long edge each, are both 87.01°. The dihedral angle between all faces is 154.12°. 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「Deltoidal hexecontahedron」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
