# List of all pairs of integers (x,y) such that # x + y is a cube, gcd(x,y) is cube-free, x >= y, |x| >= |y|, and the only primes dividing x and y lie in S, # for all sets S = {2, p}, # where p ranges over all other primes less or equal to 250. # It contains 372 pairs (x,y), some of which may appear for more than one S. # Format: "(x,y)". # Computing this list took 976 seconds. # Authors: Rafael von Känel and Benjamin Matschke, 2015. # License: Creative commons 3.0 by-nc. #
