    hello

    I have many lines like this:

    a, b, c
    a, c, b
    a, b, c, d
    a, c, b, d

    for my project, if a line contains the same letters (a, b, c, etc) but in different order, it is the same and should be deleted (one of them)

    for example:
    a, b, c
    and
    a, c, b
    are the same, so one of them should be removed

    how can I remove these?

    thanks!
