- Permutation - Wikipedia
In mathematics, a permutation of a set can mean one of two different things: the act or process of changing the linear order of an ordered set [1] An example of the first meaning is the six permutations (orderings) of the set {1, 2, 3}: written as tuples, they are (1, 2, 3), (1, 3, 2), (2, 1, 3), (2, 3, 1), (3, 1, 2), and (3, 2, 1)

There are basically two types of permutation: Repetition is Allowed: such as the lock above It could be "333" No Repetition: for example the first three people in a running race You can't be first and second 1 Permutations with Repetition These are the easiest to calculate When a thing has n different types we have n choices each time!

In Mathematics, Permutation is defined as a mathematical concept that determines the number of possible arrangements for a specific set of elements therefore, it plays a big role in computer science, cryptography, and operations research
- Permutations and combinations | Description, Examples . . .
Permutations and combinations, the various ways in which objects from a set may be selected, generally without replacement, to form subsets This selection of subsets is called a permutation when the order of selection is a factor, a combination when order is not a factor
- Definition of Permutation - BYJUS
A permutation is an arrangement of objects in a definite order The members or elements of sets are arranged here in a sequence or linear order For example, the permutation of set A= {1,6} is 2, such as {1,6}, {6,1} As you can see, there are no other ways to arrange the elements of set A

A permutation refers to a selection of objects from a set of objects in which order matters A phone number is an example of a ten number permutation; it is drawn from the set of the integers 0-9, and the order in which they are arranged in matters
