For me, the aliquot sequence 3270 in FactorDB is not being broken apart at all!
By the way, what causes the aliquot sequences in FactorDB to be getting having been broken apart? Do by that?
Erroneous computations / linkage of aliquot sequences in FactorDB is being the cause?

Is break apart being the appropriate word to use up - could be able to - consider it up - up over - not - not!

Size = length? In MATLAB programming code / GNU Octave language - size returns with in a two dimensional matrix always exactly only certainly, but not only, let not alone, length returns with in a one dimensional vector always exactly only certainly, namely - not - not!
Cause = effect?

Good work by @ Paul Zimmermann to finish off that Texas State HPC reserved 7,347+ c188 by using ECM curves running immediately, executing out, finishing off with in that composite number, which would have otherwise got no progress at all - during having been a prime number cofactor!
After 5,805L c160 and 10,366+ c172 and 6,370+ c161.

There are many different drivers (perfect numbers - all only known to be even). But there is only one downdriver!
But in each same / other case, the power of 2 must / should either be of one or of higher! Similarly for other prime number factors - numbers!
How about for the power of 0 - not - not !?

 2019-04-27, 17:37 #26 garambois     Oct 2011 24·3·5 Posts I think I found a new aliquot sequence with error on FactorDB. It's a sequence that starts with a number < 3,000,000 which is on the blue page. This is the sequence that starts with 1142360, error at index 199. Can anyone confirm ?

This is base 2, so everything ok here.

303610 = 1011110111002 = 2^2*3*11*23
-> 10 10 11 1011 10111 = 2239110

 2019-12-08, 09:54 #31 garambois     Oct 2011 3608 Posts Unless I'm mistaken, there's a problem on the blue page with the 2 sequences called "These sequences are currently broken" : the link no longer works ! In addition, the problem is solved for sequence 1142360. I haven't checked to see if sequence 1465290 is repaired.
