99 as an example (Posted on 2018-07-22) Difficulty: 3 of 5
The first 1000 digits of pi have exactly 99 appearences of "99".

The above sentence will be true if 99 will be replaced by another number.

What number(s?) ?

There are 17 appearances of 17 in the first 1000 digits of pi. In fact, 17 is the first 2-digit number to appear 17 times in pi. Also, there is a 999999 in the first 1000 digits of pi. Happy Pi Approximation Day!
