Dysprosia,
Thanks for the formatting on Lagrange's four-square theorem - I was going to get the basics in and then look around for what my pretty-printing options are. But as you noticed and I didn't, <sup> is perfectly adequate here ;-)
I'm expecting to be around for a while. Wiki's one of the most worthwhile projects I've come across in a long time, as I expect most people around here will agree.
Cheers,
Onebyone.
