Sure, Point me to where I can find them, and I will show no problems...
This is my first challenge with GPU's.
 
I used the link http://www.primegrid.com/ap.php that bcavnaugh, provided.....

I've been doing:
primgrid.com/home.php
Select Your Account on the left.
Scroll down to Active projects and the first one listed for me is AP26 tasks with the stats.

Something does not seem right...
 
I have never done AP27 before.....so maybe it is correct??

That seems about right (maybe 20's a bit low, but it's all odds...).  Surprised your 23 doesn't show up here.  That is like winning the lottery.
 
The primegrid.com/ap.php page doesn't show I've found any arithmetic progressions, so I'm guessing it only shows 23s and above...
 
Thanks for sharing.

edited, to save space.
 
Nothing to see here, move on..

This is from the AP page Bill showed the link for...

Well, it worked when I clicked the view detailed statistics link as opposed to typing it in directly (maybe it doesn't realized I'm logged in).  Thanks.
