[QUOTE=rebirther;441223]I dont understand the script. What do you mean with reformat?[/QUOTE]

He is saying that test the number as a base 5 number, not a base 625 number because the PRP test is faster even though it is the same number of bits.

625 = 5[SUP]4[/SUP], so:[LIST][*]when k is not divisible by 5, k*625[SUP]n[/SUP]+1 = k*5[SUP]4n[/SUP]+1, and[*]when k is divisible by 5 (k=5m) k*625[SUP]n[/SUP]+1 = m*5[SUP]4n+1[/SUP]+1[/LIST]

Taking S927. Have sieved for n<10k, will complete that range, then sieve the rest to 25k without any k's found up to that point.

Reserving S513 to n=25K.

R672 status update: 560k remaining at n=10k, all files sent.
74 primes found from n=10k to n=15k, 486 k's remaining.
Primes sent to Gary.
Continuing to n=25k
There are about other 25 PRPs up to now, on the way to n=25k, but those I won't know if they are primes, until the task to 25k finishes.
There might be like 2-3 weeks to go.
