You misunderstoof what I meant. What I meant is that any of the element can be put to be the first number, and since we prooved any combination can be made with three numbers, leaving the same result, thus we proved that any number that start with a certain element gives the same result and every combination gives the same result as well. Now that it is proved for 4 elements, it can be proved for 5 ans so on.
