How the search works
Positions are counted after the decimal point (position 1 is the 1 in 3.14…), overlaps count, and the depth follows the length of the sequence:
| Digits in the sequence | Searched in the first |
|---|---|
| 1 | 1,000 |
| 2 | 10,000 |
| 3 | 100,000 |
| 4 | 1,000,000 |
| 5 | 10,000,000 |
| 6 | 100,000,000 |
| 7+ | 1,000,000,000 |
Example: 12345678 first at position 186,557,266
Positions 186,557,261–186,557,280
| 0 | 5 | 2 | 8 | 9 | 1 | 2 | 3 | 4 | 5 |
| 186,557,266 ↑ | |||||||||
| 6 | 7 | 8 | 0 | 5 | 0 | 2 | 9 | 1 | 3 |

FAQ
How many digits of Pi does the search cover?
The depth follows the length of the sequence: one digit is looked for in the first 1,000 decimals, three digits in the first 100,000, five digits in the first 10 million, and any sequence of seven digits or longer is searched across the whole first billion decimals.
Does every sequence of digits occur in Pi?
It is expected but not proved. It would follow from Pi being a normal number, meaning every block of digits appears equally often, and normality of Pi has never been demonstrated. A given ten-digit combination shows up on average once in 10 billion digits — already beyond the billion searched here.
Where does the position numbering start?
At the first decimal place: in 3.14159… position 1 is the digit 1 and position 2 is 4, while the leading 3 in front of the point is not numbered.
