Hi everyone,

Today, I got an automated private message in the PrimeGrid BOINC project telling me I found a prime number in their AP27 subproject.

The message I got is the following,

Here it is in plaintext:

Dear AP finder,

Congratulations! Our records indicate that a computer registered by you has found a unique Arithmetic Progression of primes of length 21. This computer is assigned to the AP27 project. Since primes found in this subproject are not large enough to report to the Top 5000 Primes List, your AP21 sequence is visible immediately.

Workunit 574020495 : 108096152238162469+6453505523#n for n=0..20

You can select the minimum length of AP for which to receive these notifications in your PrimeGrid preferences.

If you have any questions or concerns, please contact us and we will surely resolve any problems.

Once again, congratulations on your find! Thank you for participating in PrimeGrid.

Sincerely,
The PrimeGrid Staff
