As far as i see Tarry-Cazalas method (wich i never read except the link i gave you) works on Pfeffermann's square and i find this very interesting.
If you got more about Tarry-Cazalas method please share with me.

Separate both matrix as I say above in 2 square's A and B.
Take for example number 79 in Pfeffermann's incomplete square, 7+9=16=>1+6=7 and you got the B matrix value of 79.
Do the same with all the values and create the A matrix by your formula in the same order.
Tell me what you find intersting after you do that.

Hi bobbym,

Yesterday I saw that the value of B matrix is the same as the sum of the corespondent value in the 9x9 bimagic square.

http://www.taliscope.com/LoShu_en.html

Take 28 as final value as my example, 2+8=10=>1+0=1=B.
All the square works the same.
From here by the formulas you gave me is easy to determine A matrix.

Check out this link:

http://www.multimagie.com/ (in the left side go to Bimagic Squares 9)..

..take the problem put by G. Pfeffermann in 1891(bi-trimagic square) and split the matrices as I said and you will find some interesting things going on with the the numbers graviting around number 5.

I will do that. Glad to be around.

I like it very much so i'll keep looking.

Hi bobbym,

I don't know how to generate 1 of them. Can you tell me where i can find something to read about this please!?

As far as i understand the numbers work as a vortex around 5 on clasic 3x3 lo shu. I know how to generate a Sierpinski fractal 1-81 but this does'nt helped me so far to understand how sudokus are generated.

Thank you.

Hi bobbym;

I appriciate your answer and help.

If i know one of the matrix is easy to determine the second one by the solution you give me.

Don't know how to determine both matrices if I see only the 9-th order square.

Thank you bobbym, your answer helped a lot.

Thank you bobbym.

I start to read about Lo Shu squares and I have found this way of building a 9x9 bimagic square from 2 Sudokus with the formula x(A-1)+B=y by Tarry-Cazalas method as you can see in the link below:

http://www.taliscope.com/LoShu_en.html

I was trying find out a way to determin the Sudokus if I know only the 9x9 square.

Problem is:

x(A-1)+B=y

If x=9 and y=28 how much is A and B?


Thank you.
