    Is there a number 1234567890987654321 in Pi?

    Answer

    In the first 1,000,000,000 digits of Pi, 1234567890987654321 is
    not found

    Searched in the first 1,000,000,000 digits after the decimal point, position 1 = the 1 in 3.14…, overlaps counted. If the digits were independent and equally likely, a 19-digit block would be expected about once in 10,000,000,000,000,000,000 digits — beyond the 1,000,000,000 searched.

    FAQ

    Is there a number 1234567890987654321 in Pi?

    In the first 1,000,000,000 digits of Pi, 1234567890987654321 is not found

    Does that mean 1234567890987654321 is not in Pi at all?

    No: only the first 1,000,000,000 digits after the decimal point were searched. It may occur further on; whether every digit block occurs in Pi is unproven.

    How often would a 19-digit block be expected in Pi?

    With independent, equally likely digits, about once in 10,000,000,000,000,000,000 digits; the search covered the first 1,000,000,000.
