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

Here lies the reader who will never open this book. He is forever dead.

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.

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.
