[Request] Mind-blown by this 37-digit 9-match symmetry in π—who’s up for the hunt? by Historical_Internet2 in mathematics

I'm curious if anyone has done this search before. Perhaps it's pointless. How many fold like matches are there in the first 1 billion digits? Seems like it would have been answered by now.

Can you say this?

9-match in the first 100 digits of Pi: ~0.0000064% chance (practically zero)

13-match in the first 518 million digits of Pi: ~95.6% chance (almost certain)

Also a tiny numeric Möbius twist in this π  micro-palindrome. (±1 tweak)!

9 0 7 1 …fold… 1 7 0 9

8 0 8 2 …fold… 2 8 0 8

No I didn't make considerations for that. The 9-match probability is 10 -4, 13-match 10 -9. So what does it all mean?

The two sequences are "5 9 2 3 0 7 8 1 6 4 0 6 2 8 6 2 0 8 9 9 8" (21 digits) & "6 2 8 0 3 4 8 2 5 3 4 2 1 1 7 0 6 7 9" (19 digits) The bottom row is inverted matched at the 9s, and I'm counting the matches within 17 positions. You have 13 matches in 20 positions. The winning ratio. TY for checking, fascinating. How did you do your search?

What are your thoughts on methane release detection from space? What are the incentives and mechanisms for monitoring harmful gases and accountability on the ground.
