Project Euler #109: Darts

    "There are exactly 14 distinct ways to checkout on a score of 6"... There seems to be more. For example:

    s1 s1 s1 s1 d1
    s1 s1 s2 d1 
    s2 s1 s1 d1
    s1 s2 s1 d1
    s1 s1 d1 d1
    d1 s1 s1 d1
    s1 d1 s1 d1
    

    These are not included in the list. Which rules crossed them out?
