Default AQ 10528

currently at index 4604 with 104 digits (C103 remain with still 2*3 driver)

i don't know if this was mentioned before:
at index 4494 and 4495 there're two number with 89 digits differing by only 12!!!

15526613584739423556724341246550236497122691268330093206540848184776065619780804502468574
and

not so remarkable:
at index 4592 and 4593 there're two numbers with 104 digits where the first 42 digits are equal!

are there other such remarkable small differences in 2 indices?
perhaps a new thread!?

These are rare, but not remarkable. Simply put, if N factorises as 2*3*p, then Aliquot(N) = (1+2)*(1+3)*(1+p)-2*3*p
= 12(1+p)-6p=6p+12 = N+12

Dear god what a ride 103920 has been on over the night. From a c103 to a c112 through a c13, 1400 new lines, and EIGHT different downdriver runs . It's made up for all the fun stuff by going on a truly terrifying 2^3*3*5 run now though...

Currently at index 4462.

Awesome graph.

Unfortunately, that is among the nastiest of the drivers since it increases the sequence so quickly. Bail out when your patience is exhausted........Awesome run there, though!

I have now installed aliqueit.exe and run the sequence with this program. The next (very few) lines are posted to Syds database.
I just posted another update of this sequence to the database.

The sequence is currently at size 101 with 2^5*31.

I updated 181410 (currently with the 2^2 guide) and 100436. 100436 is missing ~70 lines in between, so the newest steps don't yet show up in the database - I am currently reconstructing these lines.

Newest lines of 100436:
