Talk:Regular representation

Basic idea
This article should have an introduction to the basic idea (groups acting on themselves) before introducing more advanced structures. It links to the article on group algebras saying, "The article on group algebras articulates the regular representation for finite groups", but the article (at least no longer) has any such information.

 * I think it sort of tries to do this (group acting on itself), but it does so in a pretty huffy way. Do you mean that there should be a section before the first section, or that the first section should be improved? JackSchmidt (talk) 18:11, 24 December 2008 (UTC)


 * Perhaps a little bit of both. The first two sentences of the (current) first section should be revamped into a new first section, thoroughly defined rather than mentioned in passing.  I'll try to do this later tonight or maybe tomorrow. Rghthndsd (talk) 21:38, 2 January 2009 (UTC)

What about the most simple case?
A finite group over the complex, in which case (and maybe in others as well) there is a well known decomposition to irreducible factors? —Preceding unsigned comment added by 147.96.18.206 (talk) 10:14, 27 April 2009 (UTC)
