Are you sure about #7? I was expecting an answer similar to this: https://imgur.com/ORkgdOd Otherwise, awesome. I trust your judgement, just asking.

Hey - you are absolutely correct. Mine is correct until I used the "order matters" formula at the very end where it clearly doesn't apply here. If you follow the (correct) formula listed in your example, you get 20c4 =4,845 - which makes a lot more sense then what I originally put. My apologies for the confusion

Thanks for all your help!
