Where does what come from?

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

Re: Combinations 6 of 49 without the results with numbers in sequence

Hmmmm, the recurrence of course.

In mathematics, you don't understand things. You just get used to them.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.

I found it using some simple casework.

Re: Combinations 6 of 49 without the results with numbers in sequence

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?

Re: Combinations 6 of 49 without the results with numbers in sequence

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

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.

Re: Combinations 6 of 49 without the results with numbers in sequence

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

Re: Combinations 6 of 49 without the results with numbers in sequence

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.
