Sarcasm meter = nonexistent. :) I mean how many different bases could it really be?
A quick look at the CRUS pages would have answered the question. Karsten gave it away though. Last fiddled with by gd_barnes on 20210815 at 19:25

I thought it was a prime from another project misreported in this thread. So, when your replies seemed to misunderstand henryzz's question, "sarcasm" sure didn't cross my mind.

I guess I was wrong since 3 out of 4 people did not pick up on it. Such is communication online. Riesel base 2 2nd conjecture now has 36 k's remaining at n=1.75M as can be seen on the CRUS pages. It was announced >2 months ago that CRUS would start working on this conjecture to make it consistent with the Sierp side: https://mersenneforum.org/showpost.p...&postcount=301 There was a status report 34 weeks ago here: https://mersenneforum.org/showpost.p...&postcount=463 Last fiddled with by gd_barnes on 20210816 at 00:20

I have updated the instructions for reporting top5000 primes in the first post of this thread. It had become outdated after the top5000 site was updated.
If you are new to reporting top5000 primes please let me know if you find any problems in the instructions.
