How Feynman approached Fermat's Last Theorem

While reading more about Feynman’s derivation of the Schrödinger equation in Schweber’s book QED and the Men Who Made It, I ended up finding a mention to an undated two-page manuscript written by Feynman about Fermat's Last Theorem....

(S)ince Feynman died in 1988 and Andrew Wiles published the proof of the Theorem in 1995 we know that when Feynman wrote it FLT was still one of the most famous open problems in mathematics. What’s interesting about the manuscript is that Feynman’s approach to the problem is purely probabilistic....
