Which groups are isomorphic to s3

Here is the multiplication table where we use the one-line notation for permutations, where, as in the previous multiplication table, the column permutation is applied first and then the row permutation. Thus, with the left action convention, the row element is multiplied on the left and the column element on the right:. Further information: Element structure of symmetric group:S3. As for any symmetric group , cycle type determines conjugacy class. The cycle types, in turn, are parametrized by the unordered integer partitions of.

The conjugacy classes are described below. This group is one of three finite groups with the property that any two elements of the same order are conjugate. The other two are the cyclic group of order two and the trivial group. For an interpretation of the conjugacy class structure based on the other equivalent definitions of the group, visit Element structure of symmetric group:S3 Conjugacy class structure.

The classification of elements upto automorphism is the same as that upto conjugation; this is because the symmetric group on three elements is a complete group : a centerless group where every automorphism is inner. Further information: Endomorphism structure of symmetric group:S3. Since is a complete group, it is isomorphic to its automorphism group, where each element of acts on by conjugation.

In fact, for , the symmetric group is a complete group. Further information: Symmetric groups on finite sets are complete. Further information: Subgroup structure of symmetric group:S3.

Further information: Linear representation theory of symmetric group:S3. For context, there are groups of order 6. For instance, we can use the following assignment in GAP to create the group and name it :.

Conversely, to check whether a given group is in fact the group we want, we can use GAP's IdGroup function:. Jump to: navigation , search. In particular, it is a symmetric group of prime degree and symmetric group of prime power degree. It is the dihedral group of order six degree three , viz. It is the special linear group of degree two over the field of two elements. It turns out that, because of the nature of the prime two, it is also the projective special linear group of degree two , the general linear group of degree two , and the projective general linear group of degree two.

It is the general affine group of degree one over the field of three elements , i. It is the general semilinear group of degree one over the field of four elements , i. It is the von Dyck group with parameters , and in particular, is a Coxeter group.

In particular, it has the presentation where denotes the identity element :. In the Coxeter language, this is written as:. Multiplication table We portray elements as permutations on the set using the cycle decomposition. Element If we used the opposite convention i. Thus, with the left action convention, the row element is multiplied on the left and the column element on the right: Element Contents.
