Great dodecahemicosahedron (original) (raw)
En geometrio, la granda dekdu-duon-dudekedro estas nekonveksa unuforma pluredro, indeksita kiel U65. Ĝi komunigas la saman situon de lateroj kaj 12 kvinlaterajn edrojn, kun la konveksa dekdu-dekduedro.

dbo:abstract | En geometrio, la granda dekdu-duon-dudekedro estas nekonveksa unuforma pluredro, indeksita kiel U65. Ĝi komunigas la saman situon de lateroj kaj 12 kvinlaterajn edrojn, kun la konveksa dekdu-dekduedro. (eo) In geometry, the great dodecahemicosahedron (or small dodecahemiicosahedron) is a nonconvex uniform polyhedron, indexed as U65. It has 22 faces (12 pentagons and 10 hexagons), 60 edges, and 30 vertices. Its vertex figure is a crossed quadrilateral. It is a hemipolyhedron with ten hexagonal faces passing through the model center. (en) En géométrie, le grand dodécahémicosaèdre est un polyèdre uniforme non-convexe, indexé sous le nom U65. Ses 30 sommets et ses 60 arêtes, le long de ses 12 faces pentagrammiques sont partagés avec le dodécadodécaèdre. (fr) In geometria, un grande dodecaemicosaedro è un poliedro stellato uniforme, e in particolare un emipoliedro, avente 22 facce - 12 pentagonali e 10 esagonali - 60 spigoli e 30 vertici. (it) 大十二面半二十面体 (Great dodecahemicosahedron)とは、一様多面体の一種で、十二・十二面体の正5/2角形の面を削ったものである。 * 構成面: 正五角形 12枚、正六角形 10枚 * 辺: 60 * 頂点: 30 * 頂点形状: 5,6,5/4,6 (5,6,5,6が蝶ネクタイ形に交差する) * ワイソフ記号: 5/4 5 | 3 * 枠: 二十・十二面体 * 双対: Great dodecahemicosacron(無限遠点を含む) * 外接球半径: 一辺を2とすると2 (ja) 大十二面半二十面體是一種擬正半多面體,由12個五邊形面和10個穿過整體幾何中心的六邊形面組成,外觀看起來像每個五角星都向內凹陷的截半大十二面體。由於其每個面都是正多邊形,且每個頂點對應的角皆相等,因此也可以被歸類為擬正多面體,然而由於這個立體同時具備半多面體的特性,因此被部分學者分成一類新的立體,即擬正半多面體(Versi-Regular Polyhedra),這類立體共有九個,最早在1881年由亞伯特·巴杜羅(Albert Badoureau)發現並描述。特別地,大十二面半二十面體的外接球的半徑正好是邊長的兩倍。 (zh) |
