Impressive!

It has a 122 bit factor

ECM found a factor in curve #720, stage #2
Sigma=3385722498712908, B1=3000000, B2=400000000.
UID: nitro/haswell, M30253 has a factor: 4369956377031302093316331957913567537 (ECM curve 720, B1=3000000, B2=400000000)

Total number of curves run was 1621

Wow, lucky you!
I´ve been digging in that range as well, but so far so... bad.

Sometimes you just get lucky! It's the smallest exponent I've factored beating out 32029

Everything from 28807-30161 is now tested up to T40 and I have 3 stage 1's running at the present all for T40 testing

30169 - 2500 curves
30187 - 2500 curves
30223 - 2000 curves

Ah, that´s funny. I just had a look at the work I have queued and 30253 was actually due to start tomorrow or so. It´s also a good thing that you´ve posted the ones you´ve running, for 30223 is also in my queue. Oh well, time to get rid of them and get some fresh ones...

BTW, the smallest exp I ever factored is 20011 (B1 bound 11M).

They are all 1650 curves in, have just started 1000 curves on 30431, I ran quite a few curves in 16k-17k range but nothing so far, maybe the next one

lycorn · 2016-02-24, 22:44

Just so you know, I´ve already run over 3800 curves on 30491, and will finish the run tomorrow evening, completing the prescribed number of curves for a 3M B1 bound. You´ll probably wish to stay away from that one...

Just a warning, to avoid double-work. For a week now, I am running curves (B1=3000000) on the following: M33037, M33091, M33151, M38197. I aim of completing the bit-level, so it might take some more weeks. So far about 500 curves on all 33...s and 1200 curves on 38...

ECM work is not really duplicated or wasted.
