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}


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.
