Treebeard's Stumper
|
1997 promises to be a PRIME new year, since 1997 is the 302nd prime number (divisible only by 1 and itself), and:
- 1997 (prime) 1 997 (a unit and a prime) * 19 97 (two more primes 199 7 (two more primes) 1997 - (still prime)So, when is the NEXT year with this property?
* Technically 1 isn't prime, but it's close enough! Consider this two primes for the stumper.
