I did not see word "urn" in that page, which post in that?

Around post 2161. It is worded as a dice problem but actually it is related to a bin or urn problem that I had been trying to solve prior to that.

I have the result, but I do not yet know how to get it.

### Re: Is this cool with you?

I remember now, had the formula in form of a sum.
You got a closed form for that?

I do not think so. He has a gf and that is correct but his series is flawed. The good thing about it is it is more general than anonimnystefy's solution.

What's given in the book you were reading?

The labels have been changed to something simpler to read. That sum is supposed take for any distinguishable urns, distribute n balls with a max of k in any one of them.

Save yourself the work. It does not work.

The gf does but I am unable to extract a general form from them.

Maybe it does not have a simplified closed form.

That is probably true but if they would have published the correct sum then at least we would not need the sequence anymore!

That is what I was hoping to do but no luck. I searched for errata for the book but could not find any.

I was not looking for that solution but as I was looking through this book, which is full of wonderful answers, I saw it. What a downer!

Hi;

That's okay, I was talking about the size compared to the number of pages, takes more than average. But the book looks good, lots of new formulas!

Hi bobbym

What is the formula then?

Also, the answer to the last problem:

The limit operator is just an excuse for doing something you know you can't.
