%C The first 2 appearances of a(2) = 949129 both end at the beginning of a block of 100 digits of Pi after the decimal point. The 5th block of 100 digits of Pi after the decimal point ends with 94912, and the 6th block of 100 digits starts with 9. The 13th block of 100 digits of Pi after the decimal point ends with 94912, and the 14th block of 100 digits starts with 9.

%e a(2) = 949129 because 949129 is the first 6-digit number to appear 2 times in the decimal expansion of Pi.
