I reconstructed the missing lines of sequence 100436, so it's up to date now in the database.

That's something you have to get used to....over the last two years, I had ~30 seqeunces that I worked on and the result was only 10 sequences that gained the downdriver during that time.

And not a single termination in that time....

There hadn't been any searches this high starting sequence so I looked to see if I could find any cool ones, and have done a fair bit of work on this one, is it anything special? It has gone up and down more than any other I've worked on.

Errrrmmmm...

My update-postings seem to be consequently missed (in your last 2 or 3 updates since April 2nd) for updates in the Aliquot sequence reservations and status thread, so is this here the right thread to post my status updates?

My current status (latest unfactored line):

Sequence 10212: Index 2063, size 118, 2*3^4. About to GNFS a c116 cofactor.

Sequence 100436: index 768, size 112, 2^3. (Syd's database contains the complete sequence from the beginning to step 767 since I reconstructed the missing lines last week)

Sequence 113454: index 1234, size 98, 2^2*3^4. This sequence is running in my office (until someone switches the PC off), so I will probably not post any more updates on it in the next one or two weeks. (the downdriver has been lost on April 2nd; schickel has answered to my posting, but it did not make it into one of his updates on April 2nd, 3rd and 4th)

Sequence 181410: index 1704, size 103, Downdriver! (since April 3rd; acquired at size 117 in line 1641)

Side-sequence. Sorry.
