There are 32300 topologically distinct decahedra〔Steven Dutch: (How Many Polyhedra are There? )〕〔Gerard Michon: (Counting Polyhedra )〕 and none is regular, so this name is ambiguous. With regular faces: * Octagonal prism (uniform 8-prism) * Square antiprism (uniform 4-antiprism) * Square cupola (Johnson solid 4) * Pentagonal dipyramid (Johnson solid 13, 5-bipyramid) * Augmented pentagonal prism (Johnson solid 52) With irregular faces it can also be: * Pentagonal trapezohedron (5-trapezohedron, antiprism dual) — often used as a die in role playing games, known as d10 * Enneagonal pyramid (9-pyramid) ==References== 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「Decahedron」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.
