拟群 Quasigroup

(重定向自Quasigroups)

在数学中,特别是抽象代数里,拟群是一种类似于群的代数结构。拟群与群的相像之处是也能够进行除法运算,但拟群中并没有群所拥有的结合律。有单比特的拟群称作幺拟群或者(loop)。

Algebraic structures between magmas and groups.

In mathematics, especially in abstract algebra, a quasigroup is an algebraic structure resembling a group in the sense that "division" is always possible. Quasigroups differ from groups mainly in that they need not be associative.

A quasigroup with an identity element is called a loop.
