The only reason for not yet posting the solution itself is that I can't be sure the problem isn't from a current competition that's still open.

I thought the Mario "the princess is in another castle" was analogous: Mario gets to the end, only to find out that the princess he hoped to save wasn't there, causing him to go through another castle. It was a gentle ribbing and tacit encouragement to persevere. He countered with another Mario universe reference.

Skip, you posted earlier: "If it's correct, I ask for one word (various possible) that will indicate
that you have solved the problem already posted here."

You're confusing me, Skip.
The link you provide leads to a problem elsewhere at this site, called "Dividing a parallelogram":
what's that got to do with my puzzle/problem?
What does "one word (various possible)" mean?

And YES, my puzzle is one I saw at Puzzleup...and recently...
BUT how can I be "fishing" for an answer if I already have a solution?
OR how would I have been able to tell Secret Agent Man(!) his solution was not the maximum number?

Or is there a rule that states that the puzzles we post here MUST be invented by ourselves?

Or should I have stated: "found this at another site"?

The word "here" was a link to the problem that I was issuing (assuming that my answer was correct, giving me control), so the problem at that link was unrelated to the number problem. I explained that anyone who found a solution to the new problem could post a word here that would indicate they must have solved the problem.

The parallelogram is throwing me off.
