The upper bound does not prove that B is right. A solution would prove that B is partially right. Remember he said there was an easy way to get an answer and then from there he could get the smallest answer.

Hi bobbym

Hi;

Then please phrase things correctly else we can not understand each other. An upper bound implies an interval where an answer lies between. Had you said a solution then we would understand each other.

Also that is not the solution B had in mind.

Hi bobbym

But it is indeed a solution. And I can easily find it out and show it is true.

It is a solution but it did not use use B's method. So it does not yet answer the question.

It answers that B is correct about there being a solution.

This is what B stated and now must back up:

B wrote:

you can find a solution almost by inspection and then using some simple computational moves the smallest one.

But maybe I am not skillful enough to find the answer by inspection.

Hi bobbym,

New Problem:

Can you find any n quickly and then the smallest one?

Hi bobbym

The method I used will probably be faster than any other except guessing it correctly immidiately.

Nope! B's method immediately homed in on a solution that is

How is that guessing?!?!

And you also used the same theorem we used.

I never said guessing was involved. I said almost by inspection. You got 9^1004 -1 that is not the same as 9^502 - 1.

Also you never mentioned what method you used.
