Home Primes, Reloaded

Looking for new integers to factor, i found out that someone completed HP10(5874).

"new integers"??? What is a "new integer"? New to whom??

You might try http://homes.cerias.purdue.edu/~ssw/cun/

Since this is a thread about home primes, the person is asking about new integers that need factoring in home prime sequences.

Or that he is done with factoring HP's and is looking for something else......

I completed the above by GNFS and pushed it a few more steps. HP146 is now stuck on a C177, but I have only done minimal ECM in an attempt to break it (t45 level).

HP10(10700) terminates (P129, iteration 64)

Yes, this is what i meant. Sorry for my terrible explanation :(

HP10(1455) terminates in line 87 = P161.
Next I'm taking HP10(1408) = C157.

With M.Tervooren's FactoringDatabase it's easy as can be to hold the results (see 'Sequences' and choose the type of sequence).

The last days I've compiled Summary pages (like that ones for the Aliquot Sequences) at RieselPrimeDatabase under the new menu 'Interests'.

For now i've only done pages for Bases 2, 6 and 10, because they are most primeness or popular.

For Base 10 I have to do some more work (sizes only upto n~1300) and including more terminated n's with more data from MersenneWiki.

So to all, who will work on these sequences, please feel free to reserve and post your results here. I will update that pages from time to time.

I'm just extending the range for Base 6 to about n=10000 and factoring some of the lower Base 2 composites.

Happy hunting!

The link to MersenneWiki is dead, the current link to my Riesel Prime Database is here for all bases available but outdated, too.

In the Prime Wiki there's only a test page for base 2 but no other bases yet.

A better display/handling should be to download all current data from FactorDB and create a table using those data. But I've not yet done this because of other pages need work first.

I wrote a little script that pulls from factorDB and processes the results to some nice tables.
I don't update it very often but it has the status of all home primes base 10 2-5000 from yesterday

HP(10270) terminates after 82 steps; I used the inputs to test my current ECM and CADO-NFS setup.
