• 18:2218:22, 8 May 2012 diff hist +436 Artin–Tits group Sorry for adding yet another review paper as ref, but the HNN extension (p. 4) is not mentioned in the other two. Someone really needs to write a book on these, to include the obious stuff as well.
• 17:5517:55, 8 May 2012 diff hist +42 Subgroup series →Noetherian groups, Artinian groups: duh, got me
• 17:5417:54, 8 May 2012 diff hist +41 Artinian group Artin group and Artinian group are apparently two different things, duh.

• 22:4922:49, 5 May 2012 diff hist +4 Comma category →Arrow category: The definition of this is rather elementary and often given in the first few pages of category theory books, but perhaps it should be defined somewhere in Wikipedia as well.
• 21:1421:14, 5 May 2012 diff hist −40 Initial and terminal objects →Examples: It's trivial to see monoid this way. I don't see what clarification is needed here.
