You will have to do it by hand but why would you? Why do all that work when you do not even know whether it works or not.

I stress my approach of first having the answer. The experimental way. I have not convinced you of this yet and the remnants of your math education you are tenaciously holding on to.

I think a multivariate GF can be found for A(n,k) from the recurrence.

I proposed that recurrence as a pathway to an analytic solution, not for computation

It is not going to be easy to solve that recurrence.

I hope it doesn't. I don't have much time. We have some tests next week.

Casework is never simple and you must always be thinking of the form of your solution. Most math types are notorioulsy bad problem solvers. Just take a look at all those equations that they think are beautiful and are not worth a dime computationally.

What if this solution takes 1.2 million years to run?

I found it using some simple casework.

Hmmmm, the recurrence of course.

Where does what come from?

Well, when I ask this question the kaboobly doo will hit the fan. Where does it come from?

Yes.

That is what I mean. In Maxima?

I am just running the recurrence.

I do not know what you are doing, so how can I say.

Do you think there is a way to speed it up?

That is like music to my ears!
