In email I was told that it was found by ECM. Quite a nice result!

Paul, you and I exchanged email about this one (and others) back in November. If you keep your mail for that long, look for mine on 2011-11-06 (subject "Re: p48 factor of 7+6_299 found by ECMNet!"). One of my machines found this on 2010-06-11, but for some reason the server never sent mail about it. You noticed the discrepancy between the server and your records last November, which is what prompted our email exchange.

Ok, found this

It's your comps file that needs to be updated, as well as your tables. And by the way, three of those (8+5_218 excepted) are not your fault. Although I found the factor reports in my client logs, it appears that no email was ever sent by the server, which explains why I also didn't enter the factors into Tom's reservation service or the factorDB.
but your mail gave factors only for the four which were processed correctly once the information reached me and not for 4+3_358.

Now that the provenance of 4+3_358 has been settled I'll add it to the UPDATE file.

FWIW, I've kept almost all non-spam mail I've received over the last 15 years or so. The discarded non-spam consists mostly of material sent to mailing lists which is adequately archived elsewhere.

Thanks for this and, especially, thanks for mailing it to me as well.

It prompted me to post another update containing five new factors (the others by Serge and Bob) and to remove them from the ECMNET server. Rocke informed me that I'd failed to remove two others factored in the previous update --- they have also now gone.

There are now 545 factors remaining in the tables. There's no hurry yet to extend the tables as I reckon there is at least a couple of years work there. I'd be delighted to be proved wrong...

In particular, Rocke found several in the factordb which haven't been reported to me. As a result, I've no idea to whom I should give credit for 7+6_266, 8-5_259 and 9+5_245. The 25 factors found since the last update are given below. There are now 525 composites remaining to be completed and the ECM server at 207.192.74.4:8194 is allocating tasks with B1=43M.
