I haven't found many factors over the last few days, and haven't kept any of them as they usually were relatively small ECM factors. I remember one p51, but I haven't kept that one, either, since someone else had already submitted it.

Edit: I had an old .elf file, but it had data only up to i2998. That part agrees with an .elf file I just downloaded. I had two pages with factorizations left in my brower cache, but the factors appear in 4788.elf or 409578...8056.elf so they are not from the missing part.

Just in case:
The log file of my script, which runs ECM on the last composites of 4788.
Factors of terms 3373-3408, so only 3372 is missing.

Line 3387 was a nice shot.

I am bowing out at +1398, c112. Put one line in your elf file and you can go with aliqueit -e
Code:
 1397 .  1001777285392569572904290646390787226308237439383461254469983491988408403137367200479555518410377674168016748413824068285936 = 2^4 * 31 * 1447 * 18103888892349677 * 1922571138731027507 * 334759903278150757688691430026991 * 119793497488326129606597958143119427551092583328047
I'll run the c108 for closure.

Some factors are missing, but your factors are defintely of help to close the gap. (A c99 or a c78 here and there. Not too much trouble.)

Almost there... 3404... ...It was all the same sequence after all. That's a relief. My job is done here.

Well, the last I checked my abacus 3409+1398 was 4807
Not a really big surprise here.

the thing that I find interesting is that 2^4 has persisted since 4318 according to the find function in my browser ( and yes I checked for gaps beforehand in the range I looked at.

doh didn't look for other commonalities. not all 490 have 31^1 though some are raised higher.still seems interestingly long for one thing to persist since that's over 10% of the length of the sequences for 2^4 in a row. doh 496 a perfect number.

I put an .elf file with the last 2307 iterations in the first posting of the thread. I'll try to update it every once in a while.
