Compression works now. If you forceupdate submission form to get the updated page and submit your files, you should see something like this in the output:

Thanks, now it is really faster! My most recent submission's verification+upload took (roughly) 578 seconds.

The
a=211503116810 u=33181618540257457180379732920044712802112835201 breeder (my own find) has given 6860987 amicable pairs (already submitted), but the world record is better. In generating the relevant number sigma(a)/a*sigma(u)^2 has more than 195 billion divisors. I've found ~15000 breeders, still generating APs using them. Note that in this run I'm not checking the previously known breeders (or in special case the (i,1) type of amciable pairs), so you can still submit them. However as my db is not the most recent one there could be and in fact there is an overlap (but this gives also that not all of my AP is new, though most of them is really new). In that run I've found "only" ~75 new (i,1) type of amicable pair.

Code:
a=2^3*31^2*83*101*331*11383 u=73*7129*25450786684907*68383673694179*905743266226565715439297669731703*39841744110809900189228546018528439906893321189767 P.S. Actually, it has even more divisors, I just don't count oddeven cases (D is even, u/D is odd) which never produce amicable pairs. Last fiddled with by Sergei Chernykh on 20160406 at 17:26

There are over one billion amicable pairs known now! Awesome!

Next step is to doublecheck all these pairs and update compressed files for download. Last fiddled with by Sergei Chernykh on 20160411 at 09:51

For me the download time was normal (34 minutes) for each of these files, so maybe only the generating part was broken?
