Sarcasm meter = non-existent. :-) 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.

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

Sierpinski base 1030 in response to a Riesel base 2 prime is somehow not trying to be sarcastic?

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:

I have updated the instructions for reporting top-5000 primes in the first post of this thread. It had become outdated after the top-5000 site was updated.

If you are new to reporting top-5000 primes please let me know if you find any problems in the instructions.
