How do I know which is the next combination? I will always know how many values every object can hold and they can always hold the same number of values and therefore I also know total number of combinations. So if I am on combination (3, 2, 1), how do I know that the next combination is (3, 2, 2)?</p> <p>Object O1 O2 O3</p> <p>Comb. 1. 1 1 1 Comb. 2. 2 1 1 Comb. 3. 2 2 1 . . . . Comb. 27. 3 3 3</p>
