That was intended as a report rather than a complaint; I suspect 3270 broke this morning when I tried to upload a new factor.

[QUOTE=fivemack;442394]Sequence 3270 is broken[/QUOTE]

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!

that.

Texas State HPC has reserved that 2,2158M c193 for over six years of time without having it as being getting completed off.
May be that some one else or may be that NFS@Home or @ Ryan Propper could be able to - consider it up - up over!
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!

There are many different drivers (perfect numbers - all only known to be even). But there is only one downdriver!

Please,

Can anyone correct an error for the aliquot sequence that starts with the number 3^108 ?
There is an error at index 1575.

Is :

[CODE]1574 . 10536346489696420770680 = 2^3 * 5 * 19 * 23 * 919 * 3067 * 423931 * 504457
1575 . 15539970862145288285320 = 2^3 * 5 * 11 * 23 * 1753 * 15733 * 55677051589
1576 . 24287246194437618095480 = 2^3 * 5 * 7 * 31 * 2861 * 7489 * 130592086759[/CODE]

Should be :

[CODE]1574 . 10536346489696420770680 = 2^3 * 5 * 19 * 23 * 919 * 3067 * 423931 * 504457
1575 . 15540084064757285981320 = 2^3 * 5 * 23 * 181 * 593 * 594161 * 264867167
1576 . 21208836326841958327160 = 2^3 * 5 * 47 * 11281295918532956557[/CODE]

Thank you very much.

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 ?

[CODE]197 . 18491352962151584 = 2^5 * 19 * 3359 * 13751 * 658447
198 . 19843797224754016 = 2^5 * 29 * 953^2 * 1669 * 14107
199 . 20613286913078864 = 2^4 * 1291691 * 997398319
200 . 19324987440401776 = 2^4 * 7 * 172544530717873
201 . 23466056177630976 = 2^8 * 3 * 7 * 13 * 23 * 14598547849 [/CODE]


should be :

[CODE]197 : 18491352962151584 = 2^5 * 19 * 3359 * 13751 * 658447
198 : 19843797224754016 = 2^5 * 29 * 953^2 * 1669 * 14107
199 : 20640395098951184 = 2^4 * 1290024693684449
200 : 19350370405266766 = 2 * 487 * 19866910067009
201 : 9734785932835874 = 2 * 11273 * 37783 * 11427743[/CODE]

Yes, I confirmed and fixed it on the blue page.

Home Prime 3036 is broken

[url]http://www.factordb.com/sequences.php?se=2&aq=3036&action=all&fr=0&to=100[/url]

3036 => 22391 but should go to 2231123

kar_bon 2019-06-25 08:09

[QUOTE=SethTro;520013]Home Prime 3036 is broken[/QUOTE]

This is base 2, so everything ok here.

3036[SUB]10[/SUB] = 101111011100[SUB]2[/SUB] = 2^2*3*11*23
-> 10 10 11 1011 10111 = 22391[SUB]10[/SUB]

garambois 2019-12-08 09:54

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.

yoyo 2019-12-08 11:55

It seems that both sequences are fixed in factordb now.

unconnected 2019-12-09 10:49

BTW, 933564 is broken.
