If you can repeat digits there are are many more combinations. (1112, 1212, 1312, 1412, 1412, 2212, 2112, 2312, 2412, 2512, 3112, 3212, 3312, 3412, 3512, 4112, 4212, 4312, 4412, 4512, 5112, 5212, 5312, 5412, 5512). Now there are 25 combinations x 5 (12, 24, 32, 52, 44) which results in 125 combinations.
