He also corresponded several times with American mathematician H. S. Vandiver.
  
  ## Morishima's Theorem on FLT
  
      Let m be a prime number not exceeding 31. Let p be prime, and let x, y, z be integers such that $x^p$ + $y^p$ + $z^p$ = 0. Assume that p does not divide the product xyz. Then, p² must divide $m^{p−1}-1.$
  
  ## Review
  
  Granville wrote that Morishima's proof could not be accepted.
