what is the difference between one another and each other?
Some people say me that the difference is that in each other I am included. Other people say me that the difference is that each other implies 2 people and one another more than 2. Thank you very much!

Question

Answer

Essentially there is no difference but here are two sample sentences:

each other: two people
The members gave each other a book.

one another: more than two people
Sam, Max, and Pat gave one another a book.
