[QUOTE=mnh001;259774]Here's a bit of work for HP(7119). I'm not sure what you folks do with the results so I'll just post them here for now.[/quote]

I've inserted the new factors [url=http://factordb.com/sequences.php?se=10&eff=2&aq=7119&action=last20&fr=0&to=0]here[/url].

If you found new ones, please do so, too.

If you're not aware of it, a list of more (n < 10000 and special ones) can be found on my pages [url=http://www.rieselprime.de/]here[/url] but not yet updated for some time.

Ok, got it. Thanks.

I've brought HP(7119) up to n=74:

n=74

89 x C(158)

C(158)=37880241260441648454853019041706189816020665628579661566292717663064579587301511400983975102688716755150077517086194659599898002116732904887565392306558052587(C158)

[/code]

It's already in the database. I don't think I'll take it any further for now since it will take up too much time.

I'm working on HP(6516) at the moment.

I moved HP(11500) forward a few steps. Index 62 now has a c100. I will not be finishing that.

I also ran a t30 on c158 of HP(7119), index 74.

mnh001 2011-05-01 12:42

It appears the database is all messed up. It's not forming new numbers the way it should. Yesterday hp7119 was stalled on index 74 with a 158 digit composite. Today it's a prime at index 2. Something bad happened overnight.

mnh001 2011-05-01 15:21

False alarm. I didn't realize that I must have reloaded the page and it reset the sequence from Home prime base 10 to Aliquot, making it look totally wrong. Oops! :redface:

lorgix 2011-06-09 20:49

Progress with the following HP[SUB]10[/SUB], among others:

1519
4172
4852
4927
5632
5708
6227
6812
9339
9595

Many sequences are still very easy to move forward. p25s were plentiful in my latest batch.

HP[SUB]10[/SUB](7032, 79)= p160

edit: The only bigger termination I can see is the p196 ending 973.

9998[/CODE]Karsten, are you planning on updating your HP[SUB]10[/SUB] table any time soon?

Maybe you want to add these two to HP[SUB]2[/SUB];

HP[SUB]2[/SUB](10471, 211)= p132
HP[SUB]2[/SUB](10503, 218)= ..c136

I checked my results from the past few days, and it turns out that I have extended 48 HP[SUB]10[/SUB] sequences in the last week. But none of them were in between 2637 & 4172, a range with ~90 composites. Out of ~540 total. Oh, and the smallest was 1298.

So if you want a challenge; you might wanna concentrate on n<1298 or 2637<n<4172.
