unreserving 179328 at i=636, sz. 130, 2^2*7 driver.

c128 cofactor had ~995 ECM curves at B1=1e6 and 772 (of 1774 planned) curves at B1=3e6.

Reserving 112584.
This and 214120 need to be removed from the recommended seqs thread, they're both reserved.

Unreserving 233634 at size 125, C123. 2^3 * 3 took it all the way up there, it briefly lost the driver, and then picked it right back up again.

unreserving 112584. After some downdrivers (detailed in the status updates thread) bottoming at 78 digits, (for one line!) it hit a series of drivers, taking it out of the range of easy work.
reserving 241884, it's got the downguide, (as I'm calling it, a.k.a. 2^2) looks promising! Then again, it might turn right into a nasty driver, and I might be abandoning this a dozen lines later!

Full update!

schickel escaped 2^3 * 3 very quickly after acquiring it at 93 digits on 88662. The sequence then picked up a downdriver at 98 digits, but this was lost at 96 digits. From there, a 2^x * 3 guide type pushed it up to 109 digits, where it is guided by 2^8 * 7.

unconnected escaped the 2^4 * 31 driver at 130 digits on 102000, breaking the record for that driver of 129 digits.

The sequence is now stable at 130 digits.

Batalov acquired the downdriver at 108 digits on 199224. Sadly, the run only dropped the size to 100 digits, and the 2^2 * 7 driver was acquired at the same height, with one line below 100 digits. There has not been an escape so far.

Greebley's downdriver run on 232956 lasted until 100 digits, but the 2^4 * 31 driver took over and has driven the sequence to 112 digits.

henryzz escaped the 2^3 * 3 * 5 driver at 106 digits on 236448. The sequence is now guided by 2^4 * 3^2 * 7.

KriZp acquired the downdriver at 104 digits on 239778, and this run took the sequence down to 78 digits. The 2^3 * 3 driver was eventually acquired, but it disappeared recently at 103 digits, so let's hope there's more to come!

Sadly, we have no active downdriver runs here in the main project.

Sequences from the subproject found above 100 digits at the full update have been moved here.

Until (?) we get access to Wieb's files, I would like to reserve 363270 (sz 89) & 604560 (sz 91) to as high as I can calculate them.
