I have 20 puzzle tables (1,2,3,…,20) that contain of 10 rows (1,2,3,…,10) each. There are numbers 1,2,3,4,… in each of every tables, which has a unique position to every rows. I am just wondering if you can help me how to find the relations between them, so the next number 351,352,353,… can be placed correctly. Here I can't attach the tables, e-mail me at email@example.com if you want the tables in .xls format completely. Thank you very much for your attention. Sincerely yours, Steven Wu Bali, Indonesia.
