Hi All,

trying to find an efficient way to this in Mathematica.

I found the answer - but it was a manual list manipulation - and it
was ugly!

Any suggestions?

3 Nice Primes:

Find three 2-digit prime numbers such that:

    * The average of any two of the three is a prime number, and
    * The average of all three is also a prime number

Thanks!
