External link update
Whoever wrote this put a link in to my homepage. As I have now moved, it would be wise to update the link. I can't do it because of conflict of interest. The new link would be for the external link, and the new address would be www.maths.leeds.ac.uk/~ahubery/RHAlgs.html A Hubery (talk) 19:48, 3 February 2010 (UTC)A Hubery
