This is a slightly radical rating, but I think the article needs a bit of a shake. It is geometry in the sense of symmetry, but at present it is a list without a clear purpose or direction. This could be improved, or a different direction could be taken. In the latter case, this rating and comment should be replaced. Geometry guy 21:53, 20 May 2007 (UTC)

i didnt really understand what that means!!!!
Maybe this article should also explain the "so often mentioned but never explained" notions of "left-invariant" and "right-invariant"
Someone should add the definition of Completely invariant. Paxinum 18:36, 28 May 2007 (UTC)
