FindSequenceFunction[Flatten[ans],n]

Make sure in settings that it can not contact home. If you are using a firewall and you should be block it. This is a safety precaution. Also do not register the product or ever use it to go online. That means no contact with Alpha. Even though they want you to.

Yes, now go FullSimplify[%]

Nevermind. I used FullSimplify[Expand[%]] and it worked. Let me try for 3 bins.

It won't return any function...

The Table command has been set to return a column vector, the second column.

ans=Table[Table[f[i,j],{i,2,2}],{j,1,15}]

See that 2,2? Change that to 3,3 and you will get the 3rd column.

I did. The FindSequenceFunction doesn't return a function.

Whenever M spits out the command just like you entered it that means it did not succeed. You will probably need more terms.

But before we do that let's return to 2,2. There was more surprises there.

ans=Table[Table[f[i,j],{i,2,2}],{j,1,15}];

It is. Does it work for 3,3?

Your use of Table is not correct, change it to look like this:

ans=Table[f[i,j],{i,3,3},{j,1,15}]

Either way, it is not returning a GF...

Sometimes it is unable to answer the question and we have to try other ways.

All the work I have done is basically to coax M to give a little bit more. You can pick any problem and see some of it.

Numerical math rules!

What would you do on this particular problem for 3,3?

It is unrealistic to expect M or anyone else to get a closed form for each of those columns. A closed form does not always exist.

The first thing I would do would be to treat the numerator and denominator separately. Then we can call forth the "Oracle at Delph!!!"

That would be the OEIS?
