Math geeking

Erich Friedman wins the Geek of the Decade award. The math professor at Stetson University has posted a massive web page that lists a special attribute for hundreds of numbers from 0 to 9999. Some examples:

8 is the largest cube in the Fibonacci sequence.
26 is the smallest non-palindrome with a palindromic square.
229 is the smallest prime that remains prime when added to its reverse.
375 is a truncated tetrahedral number.
750 is the Stirling number of the second kind S(10,8).
2801 = 11111 in base 7.
3599 is the product of twin primes.
9999 is a Kaprekar number.
