S217 tested to n=400k (200-400k)

nothing found, 1 remain

Results emailed - Base released

Reserving R112 for a short effort: 250k to 300k. I'll extend the sieve from 42T to 50T or more, and then do some testing.

Reserving S107 to n=1M (500k-1M) for BOINC

Update: R112 is at 272k, will complete to 300k. Sieve file was extended from 42T to 80T.

S243 Update
 

Testing continues at n=80k. 149 sequences remain. 17 primes found (note base 3 representation):
