  • Someone has calculated the first 100 Trillion digits of pi, so if I understand the equation you’re suggesting they means it is possible to know if pi contains all permutations of all phone numbers.

    To keep the nerd going, I believe you’re over counting because not all 10 digits numbers are a valid phone number but I doubt that matters but it does reduce total number of numbers to find.

    And if we want to include international numbers the longest possible phone number is 15 digits which falls just outside the range of calculated digits 100 trillion (10e14)


  • Didn’t say anything about compression.

    Indexing and compression are not the same concept.

    If there was an index for all 5 digit sequences and their locations, it wood reduce the search space for finding a 6 digit number.

    This is about look up speed not saving space. Indexes always increase storage requirements. Always.

    The question being asked here is does pi contain my phone number? Not does pi contain my phone number with an index location whose numeric value is shorter than my phone number?
