Pi's repeats numbers all the time. Like, pi to eight decimal places is 3.14159265: that's two 1s and two 5s, or four out of nine (prit near half!)numbers are repeated.

Now, to twenty decimal places it's 3.14159265358979323846, with works out to two 1s, two 2s, four 3's, two 4's, three 5's, two 6's, one 7, two 8's, and three 9's. So you can see that the more decimal places you have the more often the numbers repeat.

I mean, geez, we've only got ten digits from 0 to 9....
