and how to use them in real life

They're slightly different from linear permutations as the total number of ways n objects can be placed in n places in a circle is (n-1)! as you fix the position of any one of the objects and find the permutations with respect to the other and if you consider their anti clock wise and clock wise permutations similar then in that case the total number of permutations becomes [(n-1)!]/2 and probably one good example is,
A round table conference is held between delegates of 20 countries. In how many ways may they be seated if two particular delegates do wish to sit next to each other.

im not sure i get that, but i do have one question about it though
like i get thats equals to (n-1)! but what is the reason for division?

@errant mountain areu there?

There are four objects so if you fix any one object and take the permutation they would happen in 3! ways and that is essentially 4!/4
