I got interested in the forum handle. It’s pretty cool.
22111 is a prime number. If you square it, reverse the order of digits and take the square root of that, you get 11122 which is the original number in reverse order.
2111 exhibits the same behavior and it’s a prime number, too. 2111 squared is 4456321. Reverse that sequence of digits to get 1236544. Take the square root of that and get 2111 backward, 1112.
Amazing what you can find in that new Google thing the kids are all talking about.
