Hello, Also sprach Zarathustra!

are primes.

And: .

Are there any other triples of primes that differ by 2?

Since is the only even prime,

. . any such triple of primes must be consecutivenumbers.*odd*

It can be shown that, in a set of three consecutive odd numbers,

. . one of them will be divisible by 3.

Crank out a list of three consecutive odd numbers:

. .

And we see that is thesuch triple of primes.*only*
