# List of all pairs of integers (x,y) such that # x + y is a square, gcd(x,y) is square-free, x >= y, and the only primes dividing x and y lie in S, # where S = {2, 3, 5, 7, 11}. # It contains 1418 pairs (x,y). # Format: "(x,y)". # Computing this list took 4042 seconds. # Authors: Rafael von Känel and Benjamin Matschke, 2015. # License: Creative commons 3.0 by-nc. # (1,-1) (2,-2) (2,-1) (2,2)
