If you answer 42x42,the answer is1 764 arrays.
You can make five arrays from the number 48
The number of arrays that can be formed with 24 counters depends on how the counters are arranged. An array is typically defined by its dimensions, such as rows and columns, where the product of the two dimensions equals the total number of counters. Since 24 can be factored into pairs of integers (such as 1x24, 2x12, 3x8, 4x6, and their reverses), you can create different rectangular arrays based on these factors. In total, there are 8 unique arrangements (considering both dimensions) for 24 counters.
Your question makes no sense.
Well, honey, let me break it down for you. To form a rectangular array, you need to find pairs of factors of 24. So, 1 x 24, 2 x 12, 3 x 8, and 4 x 6. That's a total of 4 rectangular arrays you can make with 24 tiles. Math can be sassy too, you know!
1 x 24 2 x 12 3 x 8 4 x 6
You cannot sort arrays by other arrays; that wouldn't make sense, anyway.

Oh, isn't that a happy little question! With 7 elements, you can create many arrays by arranging them in different orders. The number of different arrays you can make out of 7 elements is 5040. Just imagine all the beautiful possibilities waiting to be painted on your canvas of creativity!
Oh, dude, you can make arrays with 15 like 1x15, 3x5, and 5x3. It's like, the possibilities are endless... well, not really, but you get the point. So, yeah, those are the arrays you can make with 15.
Not counting rotations, there are 4.
