The "bug" in excel was self created, and not something that you will have to fix in your decoding if you are careful. I just ended up having the wrong formula in a cell looking up something in the wrong table and after many long hours it is hard to notice if you don't get enough sleep.

Why would the 106 highest numbers be allinclusive where the rest break down like this:

133 numbers between 6 and 988 (including multiples of the same number)
80 numbers in the 1000's category
82 in the 2000's
59 in the 3000's
80 in the 4000's
77 in the 5000's
175 in the 6000's

Along with Kain_Dracid's comment that he needed to fix an excel bug, I'm thinking this is more numerical cryptography vs. Beale cipher related.
Just something off the wall here. Are we sure that the numbers aren't the Ottendorf Cipher? Hopefully not, but ya never know.
Also, after completing the Sudoku's in this chapter, has anybody figured out there are multiple solves to a few of the puzzles, or is it just me?

3. Well, that reference I hadn't heard of before, similar to a 'book' cipher, 'Beale' cipher, 'Arnold' cipher.......
and I believe there has been previous discussion that some of the chapter soduko solves had 'multiple' answers.

The numbers could also be a form of the 1337 transfer, using numbers that look like letters. 51337 would read "sleet".

I double checked this quite some time ago. Only 1 solve per Sudoku that I am aware of.

6. Thanks for (triple) checking!! Working off memory, which typically does not serve me well (and I end up making erroneous comments like that one).

Why do I get 2 answers to some of the Sudoku's then? Which 1 do i use?

8. Not all of the 2d slices have unique solutions, nor should they. It wouldn't be much of a 3d puzzle if you could solve all of the 2d slices in isolation, now would it? You need to work the puzzle as a whole, using information from other slices to constrain your results.

I was referring to the Sudokus in the chapters...

Molnar is right, each 2D slice of the 3D Sudoku may have multiple solutions. Not until you put it all together that there becomes only 1 solution.

10. So I understand that at least one person has "solved" the numbers in chapter 13.5. Congratulations. Like most others, I am getting nowhere, but will not give up!
