(infact, mathies, whats the probability density function for string of digits length N appearing in pi's digits per M digits?) find M/N and there's your answer - might well be cheaper to express the 10000 bits themselves, than a 100,000 bit long position # in pi.
Blah. I seriously hate extending this silliness but I can't resist pointing out something that might be useful to someone to solve a real problem someday.
Who in their right mind would represent a string of 10**3000 numbers as the full string in what's supposed to be a compression algorithm? And yes, I'm pretty sure I just suggested the proper solution, as did the reference to a 255 bit array, but just in case ...
Assume that your string starts at precisely digit number 18,000,000. Advance to position 2**24, advance 1,222,784 digits further, begin recording. Obviously better/more interesting models could be developed by someone who actually cared. :)
