Conjugacy classes may be referred to by describing them, or more briefly by abbreviations such as "6A", meaning "a certain conjugacy class with elements of order 6", and "6B" would be a different conjugacy class with elements of order 6; the conjugacy class 1A is the conjugacy class of the identity which has order 1.
S 6 has exactly one (class) of outer automorphisms: Out(S 6) = C 2. To see this, observe that there are only two conjugacy classes of S 6 of size 15: the transpositions and those of class 2 3. Each element of Aut(S 6) either preserves each of these conjugacy classes, or exchanges them. Any representative of the outer automorphism constructed ...
Suzuki showed that the Suzuki group has q+3 conjugacy classes. Of these, q+1 are strongly real, and the other two are classes of elements of order 4. q 2 +1 Sylow 2-subgroups of order q 2, of index q–1 in their normalizers. 1 class of elements of order 2, 2 classes of elements of order 4.
All the reflections are conjugate to each other whenever n is odd, but they fall into two conjugacy classes if n is even. If we think of the isometries of a regular n-gon: for odd n there are rotations in the group between every pair of mirrors, while for even n only half of the mirrors can be reached from one by these rotations. Geometrically ...
We can easily distinguish three kinds of permutations of the three blocks, the conjugacy classes of the group: no change (), a group element of order 1; interchanging two blocks: (RG), (RB), (GB), three group elements of order 2; a cyclic permutation of all three blocks: (RGB), (RBG), two group elements of order 3
The irreducible complex characters of a finite group form a character table which encodes much useful information about the group G in a concise form. Each row is labelled by an irreducible character and the entries in the row are the values of that character on any representative of the respective conjugacy class of G (because characters are class functions).
Co 0 has 4 conjugacy classes of involutions. A permutation matrix of shape 2 12 can be shown to be conjugate to a dodecad. Its centralizer has the form 2 12:M 12 and has conjugates inside the monomial subgroup. Any matrix in this conjugacy class has trace 0. A permutation matrix of shape 2 8 1 8 can be shown to be conjugate to an octad; it has ...
Thus the conjugacy class within the Euclidean group E(n) of a translation is the set of all translations by the same distance. The smallest subgroup of the Euclidean group containing all translations by a given distance is the set of all translations. So, this is the conjugate closure of a singleton containing a translation.
