[QUOTE=lorgix;263861]Karsten, are you planning on updating your HP[SUB]10[/SUB] table any time soon?[/QUOTE]

I've updated my pages for HP10 and HP2 (extended to n<10800 also) with the latest results.

lorgix 2011-06-17 19:45

HP[SUB]10[/SUB](9998, 70)= p132

Other progress:
[CODE]1908
2594
2637
4790
4927
5110
5692
6333
7628
7776
7965
8222
8398
8874
9630
9685[/CODE]Relatively large factors:
HP[SUB]10[/SUB](8398, 68) ECM finds p43 with B1= 1e6
HP[SUB]10[/SUB](5110, 68) ECM finds p39 with B1= 510310
HP[SUB]10[/SUB](4067, 62) P+1 finds p38

[QUOTE=lorgix;263861]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
[/QUOTE]

I've updated my HP[sub]2[/sub]-page with all sequences <= 12000.

The two sequences from above are merges from other, lower values. See my page.

PS: The HP[sub]10[/sub]-page will follow.

Oh, ok. Thanks.

I made some progress with 2316 & 5910 btw.

lorgix 2011-06-20 22:11

HP[SUB]10[/SUB](10490, 57) has a c119, not a c106.

And progress with 10^21 & 11370.

I've updated and extended my [url=http://www.rieselprime.de/Others/HomePrime6.htm]HP6-page[/url] upto n=11000 (some sequences for n>10000 are not yet factored deeper).

I've included all terminated seqs. with more than 70 digits and listed merges, too.

Today I found the biggest termination so far for HP6 for [url=http://factordb.com/sequences.php?se=6&aq=10801&action=last]n=10801[/url] at index 102 with 144 digits.

An updated version of my [url=http://www.rieselprime.de/Others/HomePrime10.htm]Home Prime Base 10 page[/url] is now online.

RichD 2012-04-08 00:25

A spot check of a dozen or so shows all (I checked) above C110 and many much higher.

Edit: Sorry, looking at wrong column.

Will NFS@Home ever do the C181 from HP49? That number has been sitting there waiting to be factored. It'll save us a year of factoring.

debrouxl 2012-04-09 06:14

Before any infrastructure suitable for this task (i.e. probably not RSALS: a C181 is hard for the poor little 14e siever, 15e would be a better fit) takes on sieving, this number needs:
* [i]lots[/i] of ECM work, more or less t60;
* some time on polynomial selection. Other people are more qualified for giving estimates than I am, but definitely CPU-months, maybe up to one or even two CPU-years; less than that on powerful GPUs.

Has this been done yet ?

I hope not.
