The 71-bit limit has been reached. No factors. Sent to George. According to mprime the 72-bit limit will be reached at the begining of Feb. '08. Happy New Year!

Limit 2^72 reached. No factors. Sent to George. 4.56% of the run to 2^73 completed.

25% done. In fact 8 exponents 50% done and stopped. Next 8 started. ETA: March 20th.

5 test completed w/o factors. The other 11 have reached about 50%. Progress is slower than expected since I've "lost" some CPU's.
Merry Easters!!!

Results for eight exps. submitted via Manual check-ins. No factors found. TF for the next eight exponents in progress (avarage progress is about 50%). Should be ready by the end of April.
