### About the Number 59 (fifty-nine)

While creating a nBAB for the number 233, MathBabbler learned that 233 was an Eisenstein prime. During his CSC100 class on 7 April 2009, he modified the MBNA to check if a prime number is an Eisenstein prime. He noticed that he had nBABs for all Eisenstein primes less than 100 except for the prime number `59`.

The nBAB for number `59` was the first nBAB created using a MBNA that checked for Eisenstein primes.

`[Wikipedia]` `59` is a Pillai prime. A Pillai prime is a "prime number p for which there is an integer n > 0 such that the factorial of n is one less than a multiple of the prime, but the prime is not one more than a multiple of n." {OEIS.org::id:A063980}

##### Update::2009.08.11

John Hughes died at the age of `59` on 6 August 2009. MathBabbler's favorite Hughes movie was Planes, Trains and Automobiles (especially the beginning), with National Lampoon's Vacation a close second.

Note: Since the last time this nBAB was updated, the MBNA (MathBabbler Number Analyst) was modified to check for ThurmNumbers. A ThurmNumber is a number that when written in score plus number form results in a prime numbered score plus a prime number. `59` is a ThurmNumber because it is 2 score 19 and both 2 and 19 are prime numbers.
