This definitely requires a huge celebration!

I have joined the project on Dec. 2005! ... it took me 13 years, and in the last two days, I find three AP primes.

Not one or two primes but, three ... I repeat three @#&*^%\$ primes!

This is uplifting ...

With a good GPU on the job you're going to find a lot of those.
So happy hunting!

For a little more reading on what an AP is and what your results mean; feel free to take a look at the AP 27 Search thread

Finding an AP20 or AP21 (so either 20 primes or 21 primes in an arithmetic progression) requires a bit of luck. But to gain fame by finding an AP26 (will be mentioned in "official" lists of interesting APs) or even an AP27 (the world's longest (explicit) AP at present time!) requires even more luck!

The Greenâ€“Tao theorem (2004) says that no matter how long an AP someone finds, there always exists an AP that is longer.

This is not a primes, this is Arithmetic progressions of the prime numbers.
