Dries, thank you very much. Unfortunately I don't understand your 
intentions, other than that you created a list of unique numbers, right?

I am still curious if there is a smart approach. The question looks like 
what is described here:

For now I did some copy paste work with calculation of last values in 
order to get 120 unique combinations, should work.


1       2       3       4       5
1       2       3       5       4
1       2       4       3       5
1       2       4       5       3

...

5       4       2       1       3
5       4       2       3       1
5       4       3       1       2
5       4       3       2       1
