Happy #PiDay!
Fun fact: OEIS sequence A057680 highlights "Self-locating strings within pi: numbers n such that the string n is at position n in the decimal digits of Pi, where the initial digit 3 is at position 0":
For example, the number 1 occurs at the first position of pi (after the "3.") then the next number to do this is 16470 which occurs at the 16470th position of pi (though it occurs earlier at the 1602nd position)!
