Item permutations with repetition consist in the list of all possible arrangements of elements (which can be repeated) in any order.
Example: A,B,C items be shuffled in 9 couples of 2 items: A,A A,B A,C B,A B,B B,C, C,A, C,B, C,C. The order of the items does matter (A,B and B,A are counted as 2 distinct permutations).
Sets of n items are called tuples.
The generation of permutations with repetitions can be carried out using several methods:
— From the combinations of choices: all the elements constitute a multiple choice, a permutation of size n is then a questionnaire of n questions with multiple choice. The set of choice combinations represents the list of permutations with repetition.
