Is there a number 11111111111 in Pi?

Answer

In the first 1,000,000,000 digits of Pi, 11111111111 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 11-digit block would be expected about once in 100,000,000,000 digits — beyond the 1,000,000,000 searched.

FAQ

Is there a number 11111111111 in Pi?

In the first 1,000,000,000 digits of Pi, 11111111111 is not found

Does that mean 11111111111 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 11-digit block be expected in Pi?

With independent, equally likely digits, about once in 100,000,000,000 digits; the search covered the first 1,000,000,000.
