: I find this hard to believe -- did you look under the definition for the word "group"? There should be a definition like "a mathematical set that is closed under a binary associative operation, contains an identity element, and has an inverse for every element." The phrase "mathematical group" wouldn't be there, but "group" should. I'm looking at a copy of M-W right now. --[[User:Prenvolost|Prenvolost]] 11:54, 18 September 2009 (EDT) | : I find this hard to believe -- did you look under the definition for the word "group"?
