working on C74 right now

A lot of the small composites look as if they come from OddPerfect.org (p^q-1 for prime p and q). I'm working my way though them with SNFS.

Hello everyone!

I´m sorry for the problems with the factordb, plus I´ve been quite busy lately and couldnt find time to fix the issues.

The problem seem to be some numbers which were accepted as valid - but when parsed later on, they throw a "not divisible" error.

For example:
50^308%(10^19-1)/9

This error also causes the workers to exit - once they hit such a number. Page processing also stops - leaving an short status page and so on.

I´ll try to find out how this numbers could make it through now - guess some bug within the optimizer again - and give some status update here.

1013383540072335525=3*5^2*13511780534297807 keeps giving a "not divisible error". Can you fix this? (It's the number in the previous post.)

Hi Syd, welcome back! Now, if you are here, can you fix aliquot sequence 747720? (as the only one which is still wrong on the DB, AFAIK).
Thanks.

Another slightly weird issue
 

It seems that if you enter, for a number X, a potential-factor F which does not divide X but which does divide some other number in the database, the error message is 'factor already known' rather than 'does not divide'.

improvements
 

[QUOTE=Syd;256408]Sure. Just one or maybe some more?[/QUOTE]

first 5 ... &
last 3 is best for compatibility with view M numbers
sample

M607

now
P 183 (show) 2^607-1<183> = 5311379928...27<183>

then
P 183 (show) 2^607-1<183> = 53113...[B]1[/B]27<183>

Where did these 10000+ digit primes come from?
 

Where did these numbers come from?

Don't know about the first two.
