Question: Symmetric array

Good morning I'm looking for the best way to create an array with four index, let's call it V_{ijkm}, knowing that it is completely independent from the order of the index (eg V_{1234}= V_{2134}= V_{4213} =etc) and that I must use nested for cycles to initialize it, instead of a indexing function I can't guess how to insert the knowledge that the order of index in unimportant in the code Thank for any hints s.v.
