    Question Switching Numbers: infinite ordered series with two elements in the wrong order

    You are given an infinite ordered series with two elements in the wrong order (e.g. B, A, C, D, E, F, G, ....).

    A switch is the rotation of three elements in the series (i.e. B, A, C can become A, C, B or C, B, A but cannot become A, B, C or B, C, A)

    Show a sequence of switches that results in a perfectly ordered series

    OR

    Prove that such a sequence does not exist
