Is there a proof or disproof that any given finite string of digits will occur somewhere in Pi?

No, there isn't. That would be equivalent, I think, to saying that [itex]\pi[/itex] is a "normal number" and that has not been proved or disproved.

It smells equivalent to the property of normalness, but I'm not sure if it is easy to prove..
 

FAQ: Is Pi Truly Normal? Investigating the Occurrence of Finite Digit Strings

What is Pi?
