Six people are going to travel together and are going to take a group photo in front of a scenic spot. 1 person taking photos, 5 people taking photos.

1 There are six ways to take pictures. Of the remaining five people, the tallest one stands in the middle (the only one). Now, as long as you can figure out whether to leave the station on the left or on the right, the other side will be settled naturally. Total * * *: 6 * C42 = 36 species.

The hard part is that this is a combination, not an arrangement. The phrase "the group photo is highest in the middle and lower on both sides" has been arranged in order.
