WebEach of these V is an irreducible representation of G over k. Theorem 2. Every representation of G is a direct sum of irreducible representations, each of which is isomorphic to one of those V. Each V occurs in the left regular representation with multiplicity dim K V. In particular, if k is algebraically closed then each K is k. Webpartitions of n .
