I did not expect that this Solution would pass. . . . Solution 556171 was submitted on 12 Jan 2015 with Size = 65535 by unknown Player (first instance, so marked as incorrect).
Solution 557603 was submitted on 14 Jan 2015 with Size = 65535 by Michael C. (second instance, so marked as correct).
Solution 828081 was submitted on 15 Feb 2016 with Size = 65535 by unknown Player (third instance, so marked as incorrect). . . . So this here would be the fourth instance, no?
