Sorry forgot you are somewhat new to this
It looks like you can only see your own Founds, on your Your account Down under Active Projects do you show that you have any Primes?
Or Click the number even if 0 next to Primes found and you will see all of your Primes.
http://www.primegrid.com/primes/?section=primelist&userid=273570 or take my ID 273570 away and put yours to see your Primes.
 
Myself I have 9 & 7 I have 5 Primes and 11 Doublecheckers

I thought all of yours were 23
AP20: 120452772347965093+10372758*23#*n for n=0..19 (2016-11-19 07:38:42 UTC)
 
That was why I post my Founds as shown on Post http://forums.evga.com/FindPost/2585063 above#111

Nice to see a GPU focused challenge where we can shine!  Great job guys, it is a close race for the podium.
 
I'm lucky it cooled down here finally because I'm on full power with WCG + PG events...only apartment around with the window wide open for cooling!

Outside 20F at night 30F Daytime Windows are Open and 60F to 65F inside. I could not do this last week or the week before.
 
And as far as being on your Six now that is what Team Members Do! We Provide around the Clock Team Support.

AP20: 120452772347965093+10372758*23#*n for n=0..19 (2016-11-19 07:38:42 UTC)

I wish.  I think it's the n=0..19 that makes it a 20.
Below is a 22, notice the n=0..21.
AP22: 277244543103675281+3728817*23#*n for n=0..21 (2016-09-29 09:19:49 UTC)
 
I think that means this one formula yields 22 prime numbers.  Every n 0 through 21 will yield a prime number.
277244543103675281+3728817*23#*0 - is prime
277244543103675281+3728817*23#*1 - is prime
277244543103675281+3728817*23#*2 - is prime
...
277244543103675281+3728817*23#*21 - is prime
 
That is why it is so much harder to find an AP23, AP24, etc.   The whole series has to be true.  I may have read the math wrong though...
Edit: thinking about this, it must be more complicated, because it appears way to easy to get an even number using my logic.  Oh well, way to early for this thinking...
Edit 2: Couldn't stop researching...

Arithmetic progressions
In mathematics, an arithmetic progression (AP) or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant. For instance, the sequence 5, 7, 9, 11, 13, 15 … is an arithmetic progression with common difference of 2.

An arithmetic progression of primes is a sequence of primes with a common difference between any two successive numbers in the sequence. For example 3, 7, 11 is an arithmetic progression of 3 primes with a common difference of 4.

For an arithmetic progression (AP) of primes, AP-k is k primes of the form p + d*n for some d (the common difference between the primes) and k consecutive values of n. The above AP-3 is 3 + 4*n for n=0,1,2.
