It's also . = 120 Learn more about Stack Overflow the company, and our products. This is when the elements of a set can be repeated, to clarify this type, here is an example: A person goes to a candy shop, where there are 10 different flavors of candy, but this person is only going to take 4, one for each one of his children, this is an example of combination with repetition, because although there are 10 different flavors, anything disallows this person to pick the same flavor twice, trice or even four times.

September 09, 2020. Simple List of Combinations From Single Row Table Combinations without repetition of $$5$$ elements taken $$4$$ at a time: $$abcd$$, $$abce$$, $$abde$$, $$acde$$ and $$bcde$$. Permutation consists in changing the order of elements in the sequence. Let's observe first of all that, for example, the groups $$abc$$ and $$cba$$ are considered to be equal, since as has been said the order does not matter while the elements are the same. Item combinations with repetition consist in generating the list of all possible combinations with elements that can be repeated. This quickly gets out of hand if you're trying to calculate huge numbers. When these are "n" things and we make courses of action of them taking "r" at a time we get nPr plans.
