Sierp. base 73 is complete to n=100K, no primes. Results attached for 25K-100K; releasing.

Reserving Sierp. base 33 for sieving n=100K-300K.

Completed. I'll now reserve this for PRPing.

Also reserving Sierp. bae 87 for n=25K-100K.

Riesel Base 80
 

Riesel Base 80 n=25K-100K complete

Nothing found

Results emailed

Whew...and for 4 k's too. Sheesh, the high bases are tough.

You might try Riesel base 70...same # of k's and same n-range.

I was kinda bummed too. I just did that base to get rid of a couple of k's.

Sierp. base 87 is complete to n=100, no primes. Results for 25K-100K are attached; releasing.

Reserving Sierp. base 99 for 25K-100K.

Riesel Base 39
 

Riesel Base 39

Tested from n=5K-7K. 942 primes found (see attached file)

6191k's remaining + the 1 I am not testing = 6192 left

Continuing on

Well, this isn't quite as impressive as Chris's recent Riesel base 6 prime, but it is definitely noteworthy nonetheless since it proves Sierpinski base 99:

284*99^48911+1 is prime! :grin:

Results are attached for n=25K-48911.

Congrats Max on yet another proof! :smile:

A great day in CRUSland.

Nice work by both Chris and Max. More grey, less green on the conjecture pages is always a welcome sight.
