Hello,
I came here to notify that i have found a(40) in A383045.

a(40) = 1429471.

I used the code from the "PROG" section to verify this:

(20:04) gp > isok(1429471)
%3 = 1

Can you add the term in the sequence? If this is the wrong place for this, let me know.

Jaxxon.

Have you eliminated all the values between 886342 and 1429471?
If so, certainly, you can edit A383045 to add the new term.

Hi,
I already checked all of the values between those numbers, they all said no.
The PARI window crashed when interrupting it, but i can tell you that i remember that it took 5 gpu hours or less to find.
I am using pthread to find this, so the time it really took to find this was about close to an hour.
Sorry if i couldn't send you the proof.
