Would you please explain for me the difference between the “either or†and the “not both� I have hard time to understand those 2 in group games? Thank you.

@blackberry18051995@gmail.com,
Happy to help.
Rule 6 means that L is in either 1 or 9, but not both. We know L appears twice on the board, and one of the times L appears, it has to be in either 1 or 9 since those are the end aisles.
Regarding your question about "either or" and "not both," when you see a phrase that says "either X or Y, but not both," it means that if whatever is talked about is in X, then it can't be in Y. Additionally, if it's in Y, it can't be in X
X - >/Y
Y - >/X
That's how you'd write the aforementioned example. This is an "exclusive or," which means that putting a piece somewhere prevents the piece from going somewhere else.
Does this make sense? Let us know if you have any other questions!

I am sorry but I am confused on that one because the video showed the opposite of that diagram where the /X -> Y, /Y -> X. In this case, the video diagram showed /1 -> 9, >/9 -> 1
which I interpret based on the video that L can go both ends. Is it ok to assume that the one on the video diagram is wrong.

Those are both true. This is a biconditional- if L is in one then it isn't in nine, and if it isn't in one then it is in nine. That is
