This seems to use an external random number generator. I want the code to be complete and reproducible. So gimmeTheNumberAtPosition(x) will always return the same for the same x. Also, FYShuffle is much more complex than I would like the algo to be.

If you seed your random number generator, then it is reproducible.

Fisher-Yates is one of the simplest things out there IMO. Isn't the Lehmer code the thing that you want? Then you can specify your permutation with an integer and extract the individual digits from it repeatedly.

  Fisher-Yates is one of the simplest things out there IMO Just using "$n xor $something" would be simpler. I am just not sure yet, what a good "$something" is.

    How does this guarantee the desired property of the output being a permutation?

Are you saying you want a reproducible random number generator?
