As the other commenter pointed out, it's just multiples of 111. You can find all sorts of patterns playing around with a calculator, I particularly like this one:
1² = 1
11² = 121
111² = 12321
1111² = 1234321
...
111111111² = 12345678987654321
It works in other number bases too, and once you figure out the math it no longer seems that surprising.
- fuzztester 3y ago> 1111² = 1234321 ... Yes, I remember seeing that, though only up to 4 levels or so. Right, I don't think the number base has much to do with it. These are just properties of numbers. The individual cases may vary per base, that's all.
