Default Where's the big <1e6 status summary file

I'm sure there was at some point a large file posted from which I could grep out things like 'all sequences at <120 digits with current guide 2^4*3', but I can't find it poking around the forum. Could someone tell me where it is?

Might you be looking for schickel's Allseq.txt? If so the zip is available here.

If it is the one you're thinking of, be advised that there are ~1/2 dozen sequences that are wrong in the DB and consequently wrong in my file. Discussion here....

Here's a list from March of sequence, index, and digits.

When I next update the list I will try to add the current cofactor size and known factors of the last value

If I used sendspace I can also include the number and cofactor. Those entries are more data so I can't upload within the piddly forum maximum. Not sure they would be useful though.

The list is tab separated.

Made an April version so this is from last week.

It also includes a column of the factors known in the DB, so you can see what the current driver is.

I had to zip it to make it fit.

It's helpful to adjust the columns right-aligned so you can sort them easily.

Using this small awk-script called "do.awk"
Code:
BEGIN {getline}
{printf "%6d %6d %4d  %s\n",$1,$2,$3,$4}
and this DOS-batch file
Code:
awk -f do.awk OpenSeqWithFactors.out >OpenSeqWithFactors1.out
sort OpenSeqWithFactors1.out /+9 >OpenSeqWithFactors2.out
sort OpenSeqWithFactors1.out /+15 >OpenSeqWithFactors3.out
will do these things:
(The header was skipped here for convenience using the sort-command.)

- creating an aligned version of the original file ("...1.out")
- a file sorted by index ("...2.out")
- a file sorted by digits ("...3.out")

You can also see immediatly, that 920478 and 133938 terminated (see top of file "...3.out").

They were originally in excel and I just output them. With that I can sort them in any way I need.

I made them text because I got the impression that several people do not use windows all the time (Also text is more compact).

I have another output format that outputs prime vs cycle vs merge vs open ended as a status column (not 100% perfectly). I just hadn't removed the two terminations yet from the march list yet.

CSV would be a good option. Excel would read it pretty much the same and it can be parsed easily.

CSV and TSV take exactly the same file space. (csv with dquotes takes more.) TSV is more readable by eye, though.

I thought I would also post the list of sequences up to 5 Million. This is from late April in the database.

The list has the sequence number, index, current digits, approximate current number, maximum digits reached, and how many digits its currently below max. This is in a tab separated list. It was big enough to need sendspace so I didn't compress it.

http://www.sendspace.com/file/eom25w

I also have a full list of the sequences that reach 18-19 digits, including sequence number, index, status (prime, open, cycle, or number + indes they merged with), maximum digits reached (before merge if merged).

Note that cycles and Primes are rare because most sequences will merge with a previous sequence before hitting a prime or cycle. Also many cycles like 6 will never reach 18-19 digits.

They will be included if one of the following is true:
1) they reach 2^64
2) they have a single prime factor greater than 2^58
3) they have two factors greater than 2^29 in the factorization of a single sequence value.

This means a few sequences whose maximum is 18 digits and most whose maximum is 19 digit numbers will be included. Any with a higher maximum will always be included.

The summary:
