[math-fun] Salem number primes

At http://www.cecm.sfu.ca/~mjm/Lehmer/lists/SalemList.html is a list of the 47 smallest known Salem number polynomial. Here's a list of 47 small numbers. {1, 1, 1, 1, 1, 1, 5, 11, 1, 3, 1, 7, 5, 1, 1, 1, 3, 1, 1, 1, 1, 1, 3, 13, 19, 5, 1, 1, 13, 5, 1, 7, 1, 1, 41, 1, 1, 3, 19, 1, 1, 1, 1, 5, 3, 7, 1} If you take the discriminant of the polynomial and divide by the corresponding prime the result is a perfect square number. --Ed Pegg Jr
