Thank you very much for your feedback! All those are true mathematical facts, but they aren’t what I was thinking about. I am simply amazed that infinitely in both directions for winding columns of 25, the last TWO digits in each row of square numbers are the same. Also, infinitely in both directions for winding columns of 250, the last THREE digits in each row of square numbers are the same, and infinitely in both directions for winding columns of 2500, the last FOUR digits in each row of square numbers are the same. I could go on and on.
