org.apache.commons.math.random.RandomData.nextPermutation()
Generates an integer array of length k whose entries are selected randomly, without repetition, from the integers 0 through n-1 (inclusive).
Generated arrays represent permutations of n taken k at a time.

Preconditions:
- k <= n
- n > 0
If the preconditions are not met, an IllegalArgumentException is thrown.
@param n domain of the permutation @param k size of the permutation @return random k-permutation of n

@param n domain of the permutation (must be positive) @param k size of the permutation (must satisfy 0 < k <= n). @return the random permutation as an int array @throws NumberIsTooLargeException if {@code k> n}. @throws NotStrictlyPositiveException if {@code k <= 0}.
org.apache.commons.math3.random.RandomDataGenerator.nextPermutation()
{@inheritDoc}This method calls {@link MathArrays#shuffle(int[],RandomGenerator) MathArrays.shuffle} in order to create a random shuffle of the setof natural numbers {@code} 0, 1, ..., n - 1 }}. @throws NumberIsTooLargeException if {@code k > n}. @throws NotStrictlyPositiveException if {@code k <= 0}.
