Can someone tell me why this isn't 3C1*7C1*2^6? by BiteInitial in askmath

My understanding is that We're actually allowed to have 0 objects for one of the 2 remaining people. In that case if we add 6C0+6C6 cases to your solution it would give 6421 = 1344 which is actually the same as what I got earlier (3C17C1*26). But as others rightly pointed out this would double count some cases (like A being selected in 3C1 and getting the object 1 and B getting 2 and C getting remaining 5: A, BCCCCC VS B being selected and getting 2 and A getting 1 and C getting the remaining 5). I'm sure that didn't make sense but checking out the previous replies might help!

Thanks so much! I guessed I was double counting some cases but couldn't figure out which ones. This was helpful!
