my question is the following. On an cube are numbers. The numbers are v, l, r, o, u and h. The twelve absolute amounts of the differences of these numbers are the numbers from 1 to 12. The differences are from the two sides which are next to each other. So the differences are
|v - l|; |v - r|; |v - o|; |v - u|; |u - l|; |u - r|; |u - h|; |h - l|; |h - r|; |h - o|; |o - l|; |o - r|
Now I have to find out one example of this distribution. And then I have to show that the absolute amount of the difference from two opposite sides of the cube with such a distribution is not larger than 17.
My problem is that I don't have an idea to analyse this distribution, so I just can try a long time. Thank you.
