[edit]Shouldn't the generating set T be required to be finite? Otherwise you end up taking logarithms of infinite cardinals (which is possible, but not with the ordinary definition of logarithm that seems to be assumed here). Zundark 21:16, 22 Mar 2004 (UTC)
The most recent edit has omitted a few of the most elementary remarks, helpful for nonspecialists. I may put these back in, at some point.

I agree, but I think it is better now than before, in anycase the subject is a bit advanced....

[edit]The growth rate is ok, but I realized that defs of polynomial growth and exp growth here are not exactly standard. I want to fix it, but do not have books arrownd at the moment. (so I will make changes only in September) Tosha 12:42, 16 Jul 2004 (UTC)
Balls
[edit]The opening sentence says:
 In group theory, the growth rate of a group with respect to a symmetric generating set describes the size of balls in the group.
What are balls in a group? Michael Hardy (talk) 19:58, 6 August 2008 (UTC)
 I think it's referring to metric balls in the word metric Kaoru Itou (talk) 01:10, 28 December 2009 (UTC)
