# List of all solutions (x,y) of the integral generalized Ramanujan-Nagell equation # x^2 + 7 = y, where # x >= 0 is an integer and y >= 0 is an integral S-unit, # where S is the set of the first 8 primes. # It contains 16 pairs in total. # Format: "(x,y)". # Computing this list took 6 seconds. # Authors: Rafael von Känel and Benjamin Matschke, 2016. # License: Creative commons 3.0 by-nc.
