If the 3 before the decimal point is included as a digit, then the positions are in A258157.
From Eduard Roure Perdices, Jun 16 2021: (Start)
It is conjectured that Pi is a normal number in base 10, which would imply that this sequence is infinite.
In the first 10^9 decimal digits of Pi, there are 362577 permutations of {0,...,9}, and this value is close to 362880, the expected number of permutations of {0,...,9} in a list of 10^9 random integers from 0 to 9. (End)
