  1. ah yes - again the incorrect reading of the problem. We wanted four letter arrangements are there for the word Mattawa.

    Hmmm. Things get complicated.
    There is only one combination of unique letters: matw. They may be arranged in 4! = 24 ways.

    The combinations of 3 unique letters are:

    aamt
    aamw
    aatw
    ttam
    ttaw
    ttmw
    Each of them may be arranged in 4!/2! = 12 ways, giving 72 more 4-letter arrangements.

    The combinations with 2 pairs are
    aatt There are 4!/2!2! = 6 more arrangements there.

    The combinations with a triplet are
    ttta
    tttm
    tttw
    Giving us 4!/3! = 4 * 3 = 12 more.

    So, the total number of 4-letter arrangements is

    24+72+6+12 = 114

    Look ok, Damon?
