[QUOTE=biwema;188492]Thank you for the greeting.

At the beginning i was a bit afraid that it would be a big effort until all factoring tools work together. But then I was amazed that everything worked flawlessly the first time.

About the sequence 533200, i lso think i got a quite interesting one the first time. with 2*3 it slowly get larger every step and i already started thinking at which size I would give up. But then at c99 it started to decrease again, moving around a longer time betwen 20 and 60 digits and finally merged the first time at step 2799, drop below start at step 2807 and ended prime at step 2837 (Prime 43).

The largest SIQS was about 91 digits, i think.

By the way: does the word "done" in the other reservations mean. Sequence completed or unreserve because sequence increased beyond 100 digits?

In this case I reserve one more.... 534200[/QUOTE]

It's called a termination, silly. :party:

AFAIK, you are the first person ever to have terminated their first sequence.

BTW, about giving up: only take them to 100 digits, then drop them. That's the aim of this subproject.

"Done" means reached 100 digits. Usually people mention terminations, becuase they're big events. I've had two (230910 and 506154), others have had more :innocent:

531492, 531576, 531888 done

Reserving 531060, 532032, 532056

534072 done
reserving 533280

Done with 533808, 107 digits, 2^4*3^2*31
Done with 527694, 115 digits, 2^3*3*5^2

531312, 531060, 532032, 532056 done

Reserving 532180, 532252, 532440, 532530, 532656

According to the DB, 524280 is above 100 digits, so I've moved it into the main reservations thread. Unconnected, are you still working on it?

No, after a long walk I'm unreserving it because of 2^4*31 driver.

Done with 533844 - 109 digits with 2^3*3*5 - Upload to db may have failed. Db is acting odd.

527880 and 527940 done
reserving 533052, 533136
