      1234 = 24 combos

      1233 = 12 combos

      1212 = 6 combos

      1222 = 4 combos

      1111 = 1 combo

        They say: A picture is worth a thousand words:

        ABCD ABDC ACBD ACDB ADBC ADCB

        BACD BADC BCAD BCDA BDAC BDCA

        CABD CADB CBAD CBDA CDAB CDBA

        DABC DACB DBAC DBCA DCAB DCBA

        1234 1243 1324 1342 1423 1432

        2134 2143 2314 2341 2413 2431

        3124 3142 3214 3241 3412 3421

        4123 4132 4213 4231 4312 4321
