Pi must repeat

If Pi has infinite numbers following the decimal, at same point those numbers must fit into a sequence that has already been done, for whatever length of numbers.  Mathemetecians need only figure out how many numbers are repeated and for how long and in what places of the sequence.

"How do we know pi isn't some fraction of a square root, like 20sqrt(2)/9 ?"
Wtf?
Why are people with no knowledge of math posting on a math/science message board?
