Thus, it cannot be considered a permutation. So, the order is not important in this situation. If you form a group of 12 players, even if you change the arrangements of the players in the set, they are still referring to the same group. Although the persons in the picture are the same, the arrangement change makes the “pictures” different. This is an example of a permutation since every time the four persons change their positions in the picture taking, they take different pictures. This example is not a permutation but instead a combination. Hence, the arrangement of the objects in this situation does not matter. Even if we change the arrangement of these persons (e.g., Francis, Mac, and Alexa), we are still referring to the same group. Suppose we form a group consisting of Alexa, Francis, and Mac. Hence, these arrangements are counted as two different things. For instance, although 246 and 642 are essentially the same digits, these numbers are different or distinct.
