 All elements belonging to the same conjugacy class have the same order.Conjugacy classes may be referred to by describing them, or more briefly by abbreviations such as "6A", meaning "a certain conjugacy class of order 6 elements", and "6B" would be a different conjugacy class of order 6 elements; the conjugacy class 1A is the conjugacy class of the identity.In some cases, conjugacy classes can be described in a uniform way; for example, in the symmetric group they can be described by cycle structure.
