Every number is special. Here's what's [special about the first 10,000](http://www.stetson.edu/~efriedma/numbers.html) numbers (almost). For instance, "8281 is the only 4-digit square whose two 2-digit pairs are consecutive." And "5851 is the only prime so that it, its square, and its cube all have the same sum of digits."
