Got Sapphire in AP26/27 over the weekend:

 

Picked up Emerald in AP26/27 last night:

 

Just passed 20M in PPS Sieve

 

I just rolled over 1 billion points total credit in PrimeGrid on my way to 1 billion points in the PPS Sieve subproject (currently at ~778 million). This makes PG my second 1 billion point project (hit 1 billion in Collatz back in 2015).

 

Picked up Double Amethyst (1 billion points) in PPS Sieve last night. Finally.

 

PPS Sieve Double Bronze

 

My first AP25 found during the AP27 challenge!

Current AP list: http://www.primegrid.com/stats_ap26.php.

Not bad considering there are only 82 AP25s have been found.


Dear AP finder,

Congratulations! Our records indicate that a computer registered by you has found a unique Arithmetic Progression of primes of length 25. 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 AP25 sequence is visible immediately.

Workunit 587827023 : 149079784469231207+85759284*23#*n for n=0..24

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

 

The Tour de Primes has allowed me to pick up Turquoise in the PPS LLR Subproject:

 

Picked up Turquoise in Seventeen or Bust over the weekend:

 

Earned Silver for the newly revived 321 Sieve subproject:

 

Gold for 321 Sieve:

Will be hitting Amethyst in the next day, or so.

 

Well, that was fast:

 

Got Jade for GCW Sieve:

This subproject is shutting down on May 1st, so get the work now if you're interested.

Finally got Double Silver for Genefer:

I completed the work weeks ago, but had to wait for lots of it to be double-checked. Finally had the last WU I needed to cross the line validate this evening.

 

I picked up Turquoise in TRP LLR during the TRP Challenge this week:
