Lennart

Lennart has completed S7 k<=5M to n=300K. 13 primes were found and previously reported for n=100K-300K. 13 k's remain. The base is released.

R30 completed to n=500000 and released. Found primes were already reported. Residues attached, although I might have sent some of these to Gary already via e-mail.

I need something new. Reserving R23 to n=1M using the existing sieve file.

Status report
 

S10 tested till n=820000
R10 tested till n=780000

s17 almost done till 1.4M, no prime.
s19 sieved till 200k. Please reserve it again for me, so I can continue it soon. :smile:

Henryzz is reserving Riesel base 7 k=20M-30M to n=25K.

S10 tested till n=840000
R10 tested till n=800000
