[QUOTE=klajok;223974][I am not sure if it is right thread for such problem]

At page [url]http://factordb.com/search.php?id=167488215[/url] there is listed number 57 which is obviously factored, but blocks progress of sequence: [url]http://factordb.com/search.php?se=16&aq=87&action=last20[/url] , additionally in text mode of the same sequence: [url]http://factordb.com/search.php?se=16&aq=87&action=last20&fr=&to=&text=Text[/url] there is similarly number 283.

"Repair sequence" doesn't work. Is there any workaround for this issue?[/QUOTE]

Are you sure about 283? That's actually a prime, so what's the problem with this one?

This is the correct thread. We've been waiting for a fix for the 57 "bug" for a few months now (as well as other anomalies).

The "text mode" issue is still the 57 "bug," not something about the 283. The 57 just isn't shown in iteration 43 because it is considered "unfactored." See:
[code]
Sequence ended: [B]not all factors known[/B]
Unfactored: [URL="http://factordb.com/search.php?id=10144"]57[/URL]
at n=43
[/code]in the center of the page.

The "workaround" is to start a new sequence in the db using the correct composite value for iteration 44. When the 57 "bug" gets repaired, the sequence will correct itself based on matching the correct values for iteration 44.

[B]if[/B] ever... :mellow: :jail:

do ve have a list of those numbers?
i know there is 52,57 ,155,159,175,634... is there any other?
edit, found another one

Batalov gave a list in post #767!

[QUOTE=Andi47;223658]Hmmm... this is different to the email adress which I have (i had some email contact with him in spring).

I have sent an email to him before you have posted (via the email function in mersenneforum). If I get no answer in the next few days, I will try the address given in the FactorDB.[/QUOTE]

I just got an answer from Syd via email: He is currently completely rewriting the DB; he says that approx. 80% are done.

:juggle:
Some communication might be nice but at least it is happening.

1111536[/QUOTE]

I am curious why these numbers thought to be unfactored.
The first six numbers all have two diffrent prime factors, but 1111536 have four different prime factors.

from what I know, there was a time when you could qualify any number as prime even if they werent. Maybe it is a consequence of that of that (see [URL]http://factordb.com/search.php?se=1&aq=794280&action=last20[/URL] for an 'even' last term of 107 digits)

Not really, those 'small' numbers here are rated as 'C' -> composite not prime!

Here are some more (up to n=40000 complete):
[code]
52 = 2^2*13
57 = 3*19
155 = 5*31
159 = 3*53
175 = 5*5*7
634 = 2*317
1402 = 2*701
2354 = 2*11*107
4330 = 2*5*433
5034 = 2*3*839
7773 = 3*2591
9530 = 2*5*953
22274= 2*7*37*43
30031= 59*509
30518= 2*15259
32234= 2*71*227
34808= 2^3*19*229
(...)
1111536 = 2^4*3^3*31*83
