Correct a Mundo! One of the cornerstones of experimental mathematics.

It seems the the denominator is always a power of the number of bins, as expected.

Now you only have to work on the numerators. And they are integers.

But, some of the numerator might have to be multiplied by a factor.

Because it might be lost when the denominator and the numerator are canceled.

But, it is hard to figure out what the factor is for each of those fractions... What do we do now?

If you know that the denominators were powers of 3, you should be able to reconstruct the numerators.

But, the trouble is that for 3 bins and 5 balls needed, the denominator is greater than 3^4...

It seems that cancellation is not the problem. 9^3, 9^7 ... is gone!

I think the denominators have to form the series 3^(3*(k-1)).

Hi;

Not every sequence has a general term that is expressible in terms of elementary functions.

I am sure the denominators have to be of the form 3^(3*(k-1)).

That produces this table:

{1,27,729,19683,531441,...}

the denominators look like this:

You can see what was cancelled from each one and put it back.

Yes. So, the factors we need to multiply the numerator by are {1,3,9,3,9}.

You could try that. Try to read as much of the help as you can for the next couple of days.

I am going offline, I have to pay bills.

Okay. OEIS has nothing on our numerator sequence...

Even after you adjusted the numerators for the missing 3's?
