`   == Peripheral Subgroup ==  Thank you for reviewing and creating my article peripheral subgroup.  I hope people like it and improve it.      : You are very welcome of course, and thanks for writing such a decent new article. Since my own knowledge of mathematics and algebra has never been that great i think i had to click more Wikilinks in this article then in any other to figure out what i was actually reading; Still, that does make reviewing something rather interesting.  : On an entirely different matter -  if your interesting in Mathematica related articles, you might be interested in WikiProject Mathematics. Wikiprojects themselves are groups of editors with an interest in a similar topic, which collaborate on new or existing article's. Even sans the community aspect of it a wikiproject is often nice to have a look at in case you need some inspiration for a new page. (I do note that your account is rather old, so this might actually be all old-hat for you. Still, better to mention and figure that someone already knows, then just assuming one does know but actually doesn't ) )  , `
