For example let's say the first cell has this formula: =SUM(A1,B1) A1 and B1 are relative references. This means simply that when you fill the formula down, the references will change incrementally from A1, B1 to A2, B2 and so on, like this: =SUM(...
如果定义属同一左陪集(或右陪集)的2个元素等价,那么可以验证,这是一种合法的等价关系,所以陪集划分群。既然陪集的阶一样,陪集对群的划分就是一个“平均”的划分,所以有|G|=|H|[G:H],其中[G:H] 叫做子群H 对群G 的指数(index),定义为 G 中H 左(右)陪集的个数,这就是 Counting Formula。 例如, S...
