I was scanning through one million decimals of pi, and I saw a bunch of 5’s together. Using a browser search, I found that there were 2 places with five 5’s.

There is
1 instance of 00000.
1 of 11111.
1 of 22222.
2 of 33333.
0 of 44444.
2 of 55555 (where I started.)
2 of 66666
0 of 77777
0 of 88888
3 of 99999 and

1 of 999999 (6 digits).

No other number has 6 digits. It even has a name, the “Feynman Point.”

(I am selling a woman on NextDoor my HP12c for $5, and I wanted to preload it with Pi.)
