Reserving R343 and S343 to n=200k. (They sieve nicely together; two times six k's)

R343 is already upped to n=100k.
Two eliminations:
516*343^68693-1 is prime! (174160 decimal digits)
646*343^108636+1 is prime! (275428 decimal digits)

S383 and R383 is complete to n=200K and released.

Results has been e-mailed, aswell with a previously unreported prime for k=740 for S383 :smile:

Now on with my R3 reservation.

Take care.
