For example, if you are trying to come up with ways to arrange teams from a set of 20 people repetition is impossible since everyone is unique, however if you are trying to select 2 fruits from a set of 3 types of fruit, and you can select more than one from each type, then it is a problem with repetition. Item combinations with repetition consist in generating the list of all possible combinations with elements that can be repeated. where n is the number of things to choose from, and we choose r of them . Combinations of a,b,c,d,e,f,g that have at least 2 of a,b or c . Example: A,B,C items be shuffled in 6 couples of 2 items: A,A A,B A,C B,B B,C, C,C. The calculation of the combinations generates an exponential number of values and the generator require large calculation power on servers, there generations have therefore a cost (ask for a quote). Item combinations with repetition consist in generating the list of all possible combinations with elements that can be repeated. This would be similar to the combinations you can generate from repeatedly rolling a dice. We are asked to select q elements from this set, given that each element can be selected multiple times.
