Note that a repeating decimal expansion is a "pattern", but not all "patterns" in infinite decimal expansions are "repeating."

Oh granted.  I believe that the first 8 or 9 digits of Pi are found twice within the first 2 million digits of Pi.  My memory is hazy on this, but I believe that is the case.

The last time I saw an article about pi after it was calculated to the gagillionth place yet again was that there a lot of interesting strings, patterns and repeats. Of course, we could probably expect such with a random number that long too.
