Permutation According to the first meaning of permutation, each of the six rows is a different permutation of three distinct balls In mathematics, a permutation of a set can mean one of two different things: an arrangement of its members in a sequence or linear order, or the act or process of changing the linear order of an ordered set.

In English we use the word combination loosely, without thinking if the order of things is important. In other words:
Permutation 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. Note: In Permutations, order matters; for example, (2, 1) and (1, 2) are counted as different.
