The Wolfram Mathworld page on Pi Digits lists URLs of the the OEIS sequences a(n) for first occurrence of n consecutive decimal digits d, d = 0 to 9, in the decimal expansion of pi.

The largest value of n in any of these, however, is n = 14, for d = 0, 5, 7, and 9. These are in the first 1.21 x 1013 digits.

I suppose there might be a small chance of finding a(15) in one of these sequences among the first 6.28 x 1013 digits.

"Records are made to be broken. In 2019, we calculated 31.4 trillion digits of π — a world record at the time. Then, in 2021, scientists at the University of Applied Sciences of the Grisons calculated another 31.4 trillion digits of the constant, bringing the total up to 62.8 trillion decimal places. Today we're announcing yet another record: 100 trillion digits of π."
