    This is the same as asking how many distinct permutations are there of the
    letters OAWA.

    If all the letters were distinct there would be 4! such permutations, but in this
    case this will count each permutation twice as there are 2! permuutations of
    the A's counted for each distinct perm of the letters.

    Around 10 is not an adequate answer. If you don't know how to do the problem but want more help than given ask, otherwise remain silent if you
    have nothing useful to say.
