If you answer 42x42,the answer is1 764 arrays.
You cannot sort arrays by other arrays; that wouldn't make sense, anyway.
Not counting rotations, there are 4.

Well, honey, the number of arrays you can make out of 20 really depends on how you slice it. Technically, you can make 20 arrays of size 1, 10 arrays of size 2, 5 arrays of size 4, or 1 array of size 20. So, you've got options, darling. Just pick your poison and get slicing!

By using the library function #define A[] we can define the size of arrays
4 (or eight if you count transposed arrays as being different).
One.
