Subproject #3: 700k-800k sequences to 100 digits - Page 56

frmky · 2010-01-19, 20:14

788910, 788964, 789090, 789120, 789288, 789402, 790110 are done.

I find it hard to believe that an 83 digit number, ending in 7760 is prime, so I'll reserve 791196 and work it for the sub-project, in anticipation of the db being straightened out.

Of course, my advancement of the series will rely on the belief that the lines prior to the last one have no mis-labeled primes...

short version:

791196 has been vandalized

reserving 791196, anyway

For those who may have noticed that my avatar is spinning counter to the proper rotation, it is an optical illusion, due to the incompatible shutter speed with which the galaxy was originally recorded.

Aliqueit should spot any "primes" that are actually composite.

790308 is done. Lines after the incorrect one have been submitted to the database and should be picked up once the error has been fixed. The ELF is attached.

794196 appears to be finished for the sub-project, but also vandalized...

reserving 793968

I'm going to cancel the 3 I reservered here so I can do the other project. There are practically done though I think they are c99 and c100, I submitted everything I did.

Can you please attach the .elf files here? (preferably zipped, in more than one post if necessary) All three of those have been vandalized in the DB. Only 789740 was already at 100 digits before being vandalized. (if you don't have it past index 708, you don't need to post its elf file)
(for now, I've removed your reservations on them, but haven't reposted them; so I don't forget them, they are 789534, 789740, and 789816)

what does vandalized mean, the server should be able to check if something is a factor or prime? ill stick them on to this post. i must have lost the third one

Some malfeasant out there has been using the "Set Prime" button (access to which is granted manually to "trusted" DB users, though somehow it got in the wrong hands by accident) to mark known composites in Aliquot sequences as prime, which throws off the entire sequence by filling it with junk data.

Fortunately, Syd (the DB admin) has now got word of this and turned off the "Set Prime" button across the board. Therefore there shouldn't be any more vandalism, though there's still a number of preexisting instances of it that he'll need to clean up as soon as he gets to it.

And 790248 is done. The ELF is attached for when the DB is fixed.

Actually if you submit the full sequence, then usually after it is fixed the full sequence appears. In other words order doesn't matter.
