Compound of three octahedra
http://dbpedia.org/resource/Compound_of_three_octahedra an entity of type: Abstraction100002137
In mathematics, the compound of three octahedra or octahedron 3-compound is a polyhedral compound formed from three regular octahedra, all sharing a common center but rotated with respect to each other. Although appearing earlier in the mathematical literature, it was rediscovered and popularized by M. C. Escher, who used it in the central image of his 1948 woodcut Stars.

In geometria solida si chiama composto di tre ottaedri un generico composto poliedrico che sia costituito da tre ottaedri. Nel caso particolare in cui i tre componenti siano congruenti, regolari e disposti con simmetria ottaedrale, allora si ha un composto omogeneo sulle facce, che è il duale del composto uniforme di tre cubi.

在幾何學中，三複合正八面體是一個由3個正八面體所組成的幾何結構，在這個結構中，每個正八面體都將對於其他正八面體有一個相同旋轉中心的旋轉關係。其最早於布鲁克纳在數學文獻中提及，後來被莫里茲·柯尼利斯·艾雪用此形狀於1948年創作了木刻作品《群星》。
