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

Hi;
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.

How de you place 8 queens on a chess board so that does not attack each other?
(I found 64 solutions)

Re: Is this cool with you?
New problem:
A group of teachers is preparing examinations. Each test contains 4 different problems, chosen from a master list of 15 problems. Two different tests have at most one problem in common. What is the biggest number of tests that can be formed?
A says) 123454321 different tests.
B says) How did you come up with that?
A says) Parity and the properties of hyperharmonic series.
C says) Darn good answer A!
A says) Thanks, but the hyperharmonics are my specialty.
D says) I did not get that A. I counted them up and got...
A says) Hold on right there D. There is your mistake. Computation can never replace pure mathematics.
E says) You hold on, you are saying that he counted wrong?
A says) Counting, Schmounting! It is not whether or not you get the right answer but how beautifully you structure the answer that counts.
E says) Or mangle it as in your case. B, what did you get?
B says) I got 1351350 but I am not sure.
What do you get?

Re: Is this cool with you?
Thanks!
I was wondering if there's a generalization to this.
From oeis, for selecting 2 questions, the sequence is called Tritriangular numbers, but could not find anything beyond 2 questions.
Nice problem!
