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.
If we would just consider conjugacy with respect to isometries, we would not allow for scaling, and in the case of a parallelogrammatic lattice, change of shape of the parallelogram. Note however that the conjugate with respect to an affine transformation of an isometry is in general not an isometry, although volume (in 2D: area) and ...

Different music exam boards may have different grade levels for instruments and music theory. There are also music exams which do not follow the graded system, but have other designations. For instance, the Royal School of Church Music 's Voice for Life training scheme designates levels by color (White, Light Blue, Dark Blue, Red, Silver, Gold ...
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 ...
In mathematics, a group is said to have the infinite conjugacy class property, or to be an ICC group, if the conjugacy class of every group element but the identity is infinite. [ 1 ] : 907 The von Neumann group algebra of a group is a factor if and only if the group has the infinite conjugacy class property.
After a controversial couple of years in the Chapin-Irmo area school district, nine candidates are running for seats on the Lexington-Richland 5 school board.
In abstract algebra, a conjugacy class sum, or simply class sum, is a function defined for each conjugacy class of a finite group G as the sum of the elements in that conjugacy class. The class sums of a group form a basis for the center of the associated group algebra .
