It says, "Order of an element of a group. Suppose x∈G and there exists a positive integer m such that xm = e, then the smallest possible m is called the order of x. The order of a finite group is divisible by the order of every element."
What is e? Is e∈G true? dave 21:07, 8 Sep 2004 (UTC)
e is the identity element of the group. So yes, e∈G is true.
