From: Lawrence Paulson <lp15@cam.ac.uk>
I’m happy to announce a new AFP entry, by Anton Danilkin and Loïc Chevalier: the Three Squares Theorem of Legendre. This result gives necessary and sufficient conditions for a natural number to be represented as the sum of three squares of integers. it’s a simple sounding result with a long and tricky proof.
