Talk:Glossary of group theory

From Wikipedia, the free encyclopedia

It says, "Order of an element of a group. Suppose x∈G and there exists a positive integer m such that xm = e, then the smallest possible m is called the order of x. The order of a finite group is divisible by the order of every element."

What is e? Is e∈G true? dave 21:07, 8 Sep 2004 (UTC)

e is the identity element of the group. So yes, e∈G is true.

[edit] Glossary Symbology

I am working on a Sudoku maths page, and will be working through (as in referencing, using) the Group theory articles. I would like to incorporate the symbololgy (denoting symbols) from the other articles in the/this glossary. If no one objects, I will do so. Principally I don't like duplicating info, which creates an update sync. headache, but here I think it's appropriate. --LarryLACa 17:02, 9 October 2005 (UTC)

[edit] Notation

Would it be appropriate for this page to explain the notation it uses, or at least link each first instance of a notation to page where that notation is explained? I am thinking in particular of the notation of S within pointy parentheses, with which I am not familiar, and which I don't know how to type here without adding strikethroughs. I am sure I could find it, but I think it would make sense for the page to do that work for the reader (in terms of explaining the notation, not the strikethroughs, obviously). 69.205.34.127 (talk) 03:30, 2 February 2008 (UTC)pj.deBarros@gmail.com
