Very cool. I am a math nerd.

The next year that's the square of a Kaprekar number will be exactly a millennium from now: 55^2 = 3025, 30+25 = 55.

in 3025, there will be no human on this planet, even if there is, noone will care about what year it is or kaprekar number, so doesn't matter

I can't wait!

Now this I did not know. Much more useful than years simultaneously square and triangular, which we’ve missed by 800 years and have to wait another 39,591 years to pop up again. (I think; tapping into my teenaged geek years, about 800 years ago.)

Numerology has it as 9, same vibe as the year of the snake. Another very malleable & useful kapreka number. And 3 cubed....delicious all 'round.

It's also the result of (1+2+3+4+5+6+7+8+9)squared. Which I think is pretty cool

Also, it's the sum of the cubes of those numbers too. 😄

(1³+2³+3³+4³+5³+6³+7³+8³+9³) = 2,025

Isn't this always true for a triangular number squared?

brasidas.bsky.social•74 days ago

Another pattern that’s a mere millennia from the next number in the series!
