After waffling around at 114 digits for a short while, 151752 hit the down-driver. It remains to be seen how far it gets.

I updated a bunch of side branches in the database below 1 million. They are mostly quite short - going up to a trillion and then back down again for the most part.

The eventual ideal would be that you can type any number from 2 to 1 million and see the full known sequence rather than have it reach some small value and stop leaving its fate unknown.

It would also help with finding the longest known (side) sequence below 1 million. There won't be a value that waffles in the low values and joins a long sequence that the db doesn't know about.

I just discovered the Aliquot sequences a couple of days ago and have found them to be quite interesting!

I took a look at Karsten's page and I saw that there were some unreserved sequences that I thought could be extended easily in Syd's DB. Therefore I have begun working on:

117348 - Shows an index of 1358 on Karsten's page but was only at ~1140 in the DB. I now have it up to 1225.

117738 - Was stopped at index 733 with a C80. I now have it at 764 and just finished sieving a C90.

233106 - Was stopped at index 1662 with a C95. I now have it at 1671.

233320 - Was stopped at index 477 with a C88. I now have it at 479 and am currently sieving a C98.

233324 - Was stopped at index 1959 with a C98. I now have it at 1962 and am currently sieving a C95.


I'll report a status at least once/week and will continue all of these until I encounter a C100 or higher. Msieve will take out anything C85-C99 that doesn't fall by earlier curves.

cool Gary, i think the seqs are quite a contrast to PrimeSearching!

for the Summary-pages:

there're many seqs without the full data in the database but displayed at the Summary.

for 117348 i've uploaded upto index 1358 as displayed.

please have a look at the 'Aliquot ranges and status' thread to see the 'current' status.

for 100000<n<220000 i can upload data if needed (from Frank's site).

Do you mean "Aliquot sequence reservations"?

no, not really.

for new seqs he should look there for the highest level done.

BTW: it would be helpful to insert the page-link to Frank's 100000<n<200000 there!
