Hey anon! Nice job, that's absolutely correct. It's how I went about it as well. Though of course we don't need need to think about 3-1-1 and 2-2-1 as for larger numbers it might be challenging to find all such possibilities. We could just give one flag to all poles and then distribute the rest using stars and bars. For this case give every pole one flag. We're left with 2 flags and 2 bars, giving us 6.

Thank you a lot for your time and effort solving this problem. And an extra thank you for your image and explanation of your solution. I really appreciate it. I hope you have a fine day!

I have read the combinatorics part of this book. I thought it was quite good. I can't really comment on the other parts about graph theory and infinite combinatorics but the combinatorics part had good topics, examples and exercises. Has some funny jokes too, i genuinely laughed out loud while reading sometimes.
