Conjugacy classes of dihedral group
dihedral Polygon Group Mathematics
In mathematics, a dihedral group is the group of symmetries of a regular polygon, which includes rotations and reflections. Dihedral groups are among the simplest examples of finite groups, and they play an important role in group theory, geometry, and chemistry. The notation for the dihedral group differs in geometry and abstract algebra.

We compute all the conjugacy classed of the dihedral group D8 of order 8. We simplify the computation considering the centralizer of each element.
