Group actions and universality

Posted by Martin Orr on Monday, 27 April 2009 at 13:23

This continues my earlier post on groups and actions. I want to think some more about Cayley's theorem, and describe how it provides an example of a universal property. (With regard to James's comment on that post, I think universality may be a better way than injectivity of describing my concept of "active group" but I'm not sure how to do that in full).
