Regular representation of a group; its relation to the permutation group; showing that regular representation is reducible and contains all the irreducible representations of the group with degeneracy given by the dimension of the irrep; example of dihedral group D^3.


Conjugacy classes; character tables.


Determining all possible irreps of a group using these concepts.
