How do you find repetition?
In general, repetitions are taken care of by dividing the permutation by the factorial of the number of objects that are identical. If you look at the word TOOTH, there are 2 O’s in the word. Both O’s are identical, and it does not matter in which order we write these 2 O’s, since they are the same.
How do you solve permutations without repetition?
The formula to calculate all permutations without repetitions of the set {1,2,3} is n! (n−r)!
Is there repetition in combination?
Any selection of r objects from A, where each object can be selected more than once, is called a combination of n objects taken r at a time with repetition. Two combinations with repetition are considered identical if they have the same elements repeated the same number of times, regardless of their order.
What is combination without repetition?
The combinations without repetition of elements taken in are the different groups of elements that can be formed by these elements, so that two groups differ only if they have different elements (that is to say, the order does not matter).

How many permutations of 4 are there?
Therefore, there are 4· 3 or 12 possible ways to choose two letters from four. ab means that a was chosen first and b second; ba means that b was chosen first and a second; and so on. Thus the number of permutations of 4 different things taken 4 at a time is 4!.
