[URL="http://primes.utm.edu/primes/page.php?id=95017"]8*3^896701-1[/URL] (427837 digits) is prime.

This proves R729 (in other words: 24*729^149450-1 is prime; it was sieved to 150K :rolleyes: lucky, lucky...)

P.S. It remains to be seen if it is the smallest (with PFGW 3.3.6 in some ranges), but still - looks good to me. I ran it since February, on and off.

Now here's a contrast to Serge finding a prime at the end of his sieve file.

10*879^25003+1 is prime - First test out of the box

I wouldn't worry about it. The conjecture states that a prime must be found, but not that it has to be the smallest prime.

The following are complete to n=25K and released:

R706; k=83 & 155 remain; highest prime 174*706^18016-1
S686; k=116, 130, & 211 remain; highest prime 151*686^13722+1
S718; k=3, 69, 108, 153, & 222 remain; highest prime 18*718^4204+1
S730; k=84, 85, & 154 remain; highest prime 132*730^11966+1
S1009; k=46, 144, 246, & 294 remain; highest prime 276*1009^5004+1

That completes all 5kers (at n=5K) to n=25K. Now working on the 6kers.

Riesel 603 is complete to n=25,000. Exhausting.

The relevant files have been sent to sent to Gary.

Lots and lots of k-values remain.

I don't seem to have gotten an Email on this.
