"or" in Sequencing Logic Games

Doing a quick review of concepts that I struggled with early on.

I remember the following rule being simple to diagram:

L is before M but after K.

K-L-M

But I also remember that there is another type of rule that is similar to the above but it involves and "or". I think it goes like this:

K is before M or after L, but not both.

M-K-L, or L-K-M?

Does anyone know what I am referring to? If so, could you link to the lesson or a game that highlights the above?

I can't remember where it came from but the difference between the two above really stumped me at some point....

    I don't specifically recall, but I don't know if I agree with your diagramming of "K is before M or after L, but not both". I think you are omitting a few results?

    If K is before M, it would have to be before L. So
    KML or KLM

    If K is after L, it would be after M. So
    MLK or LMK

    Basically to solve it, I think you would just need to split the game into two different boards.

    One where you specify:
    K-M and K-L

    The other would be:
    L-K and M-K

    I can't recall a specific game either, but I would write this rule

    K is before M or after L, but not both.

    as follows:

    K ----- M or L ----- K but not both

    K ----- M
    　＼L

    or

    L ----- K
    M／

    Yep I agree. That's how I diagrammed it as well. As long as you ( @nyc2dc2ca ) make it clear to yourself that each diagram is an entirely separate outcome, this diagram should serve you perfectly for solving this style of game.

    @Mellow_Z Thanks for that clarification. I think that is exactly the mistake I made that I took note of and am now trying to figure out. Thanks for pointing that out!!
