Is there any restriction on the other two numbers? For example, can they be one number that is already repeated? Can they be the same number? – Sofía Marlasca Aparicio Sep 23 '17 at 08:29

Nope, they cannot be the same number so there'll be 4 different numbers in total – Tarisara Chansue Sep 23 '17 at 08:31

When you say digits, do you mean that they are restricted to $0, 1, 2, 3, 4, 5, 6, 7, 8, 9$? – N. F. Taussig Sep 23 '17 at 10:30

Yes, only 0-9 :) – Tarisara Chansue Sep 24 '17 at 12:21
