    Default pair , set, combination

    There are three pieces of data, A, B, and C.
    X is defined as a difference between A and B, between B and C, or between A and C.

    If X is defined as a difference between A and B,
    Y is defined as a difference between B and C, or between A and C.
    If X is defined as a difference between B and C,
    Y is defined as a difference between A and B, or between A and C.
    If X is defined as a difference between A and C,
    Y is defined as a difference between A and B, or between B and C.


    I want to express the above relation.
    This is my draft.
    "X is defined as a difference between any pair of A, B, and C.
    Y is defined as a difference between another pair of A, B, and C."

    Is my draft correct? Is there possibility for misunderstanding?

    Default Re: pair , set, combination

    I'd do it like this:
    "X is defined as a difference between any single pair from A, B, and C.
    Y is defined as a difference between the other pairs from A, B, and C."
