Those are certainly impressive.

Hurrah, after weeks of nothing from P-1 I finally get one at 6:47am on New Years Day.

7233758839303943 | 24737*2^10645207+1

P-1 = 2 * 11 * 29 * 97 * 271 * 2333 * 184879

[Greenbank]

1058699706255400291 | 33661*2^10649232+1

p-1 = 2 * 3 * 5 * 29 * 193 * 7607 * 28549 * 29033

Just found with ECM @ 25 digits

6112285295043972389 | 67607*2^7691+1

which was the 4th smallest unfactored n for k=67607

I'm doing P-1 on 200000 to 250000 but I just submitted these factors:-

110339071626803 | 33661*2^224160+1
4802938257372379 | 55459*2^228718+1
3068443382948634853 | 21181*2^231548+1

without logging in. Should be assigned to user 8141. Ta.

ECM found a factor in curve #3, stage #2
Sigma=5670788764645674, B1=7400, B2=740000.
10223*2^96221+1 has a factor: 278687290515007924794729914252113

33 digits. And ECM reports it as being prime. Biggest for us this year.

Good work but I'm afraid it is composite:-
