You can get the status of 10000-100000 here. Note that
Code:
12012 1710. 2  C97 sz 97
is wrong: this was the old status of 10212, and 12012 was a typo that was never removed. Note also that 11280 has its old status from before when a typo was discovered in the earlier work.

Speaking of 10212 - I have picked up this one again and will do a few more iterations, but I don't plan to take it very far... (well... I might change my mind if it gets rid of that 2*3 driver.)

 2009-06-06, 14:46 #36 Greebley     May 2009 Dedham Massachusetts USA 3×281 Posts Thanks for updating the list! I did notice for some of the 10000 - 100000 range were not in the database. For example, 10344 only goes to 74 digits. Is this because someone else is doing the 10000 -100000 range? I was curious about what was the lowest sequence for which work done is NOT in the database, and 10344 appears to be the answer.

It actually goes to 78 - the size of the initial composite is not the size of the remaining composite.

Clifford Stern maintains the 10000-100000 range, and he is constantly pushing the sequences in it higher. However, he has not put all that work into the database.

 2009-06-08, 15:29 #38 kar_bon     Mar 2006 Germany 55508 Posts now all seqs for 10000 < n < 100000 are shown on the Summary pages, too. but: the listed depths are mostly not in the database, yet. same for n>250000. so, i think, for a first milestone, all open (and some ended) seqs for n < 300000 are shown on those 3 pages! next steps: - check data with database - insert more seqs in database - stats/odds page - try to 'hire' Clavier, Stern, Zimmermann, Bosma, Creyaufmueller and other contributors for this forum/database to share their results suggestions?

Not sure if this is useful, but it is a list of the numbers that reach 1 quadrillion(10^15) before the merge with an earlier sequence or terminate.

The list is of the form:
<number> | <maximum> | <merged or maxed>

The maximum is pretty low. I used 8 byte numbers with trial division up to 2^26 from a program I wrote before finding this group. However, since 1 quadrillion is less than the square of 2^26, all sequence reached 1 quadrillion. In fact they only stopped when going over 2^64, or some factor was greater than the max prime squared and no prime divided it.

I included this because it has the 3740 numbers that might be significant and includes ones that may have been weeded out because they merged at some point after 1 quadrillion. I don't know if you want to put these numbers into the list, or whether you already have this info, but I figured it wouldn't hurt to mention it.

Out of the 3740, 113 merged with a previous sequences given the limits above.

I also have a list of:

Those that reached 1 trillion, but not 1 quadrillion. (340 numbers)
Those that reached 1 billion, but not 1 trillion. (662 numbers)

Edit: Do we need to do anything when the DB has a newer status than your page? e.g. 123450 Last fiddled with by Mini-Geek on 2009-07-04 at 12:26
