    Set theory clarification

    A = { a, b, c, d, e, f, g}
    Expression: x = y such that x, y are in A

    can x in A refer to the same thing as y in A or can it necessarily not because of the notation x, y in A?

    Next time try to word this clearer. Is what you're saying that if I in some context said " x\in A" in close proximity to " y\in A" do x,y have to be disntinct?

    The answer is no.
