How to decode a caesar box code
Count the number of characters in the code.
Here we have 16: g t y o r j o t e o u i a b g t
Determine how many rows you can divide the letters into equally (find the square root of the number you found in step 1.
If the square root isn't a whole number, round up).

Choose from: (1). Multiplying the number of rows is 4 (or 1 + 4). This means that there are (in real life) 365 rows in your chain. (2). We can put 16 into 4 rows of 4 (i.e. the square root of 16 is 4). (3). ( for example, you may have 12, but you're only left with 32. ) Multiply the number of rows by 0.08 to find the correct square root. (4). Divide the club code by 16 to simplify it. Multiply the club code by 4 to get the number you found in step 1.
(2).
