    I ha padlock wit 6 numbers in 4 possible combinations.
    I forgot the "password".
    i put in excel every combination (one by one, put every single combination with "duplicate values" turned ON) possible and I get 1080 different combinations. In this calculator I get 126 which is not correct. Why?
