A permutation is a specific arrangement of a set of items or elements. In mathematics, particularly in combinatorics, permutations refer to the different ways in which a subset of objects can be ordered or arranged. For example, if you have a set of three items, say \( \{A, B, C\} \), the possible permutations of these items are: 1. ABC 2. ACB 3. BAC 4. BCA 5. CAB 6.
