Weekend number puzzle

I haven’t offered a puzzle in a long time (some readers may recall many on game theory, among other topics, from last year). Here’s one for this weekend. I’m also including some hints, in case you want them. You can get the answer from Google, but if you want to cheat, save yourself the trouble and just read this blog on Sunday when I will deliver the answer.

Question: What’s so special about the number 10,213,223?

Here come the hints. Stop reading if you don’t want them. To distract yourself from reading the hints, go here for more integer fun.

Hint 1: Don’t do any math. Do more English.

Hint 2: Remember the “look and say” sequence?
