Have you modified the line already [I]after [/I]you started the test?
If so, this would be the reason.

A running P95 process:
1) does not re-read the worktodo.txt file (if it is modified while the program is running). In fact, if you modify the worktodo.txt, save it, [I]then[/I] stop P95 and then check [I]what[/I] is in the worktodo.txt file, you will find that it will be [I]restored[/I] to what it was before, when P95 was started. This is done from P95 memory at the moment when it is stopped. This is unusual for new users, but once you learn this feature, you can live with it.
2) can use the intermediate save files (the "m" and "e" files) from the run before this one (and the save file doesn't know that you changed the worktodo line, and will continue from the earlier state, i.e. without the listed factors). Solution: remove these files (or move them to another directory).

I have just run your line as is in P95 several times. The known factors were not found even once (which is just what one would expect).

P.S. In fact,
ECM found a factor in curve #22, stage #2
Sigma=3698465552502853, B1=50000, B2=5000000.
M119923 has a factor: 68966518357695541070447 (ECM curve 22, B1=50000, B2=5000000)

Why running ECM on numbers with [U]already known[/U] factors if we still have so many numbers without any known factors? Wouldn´t it make more sense to run ECM on those?

Maybe he wants to beat [URL="http://www.primenumbers.net/prptop/searchform.php?form=%282%5Ex-1%29%2F%3F&action=Search"]NOOE's PRP records[/URL]? Who knows?

Just in case,

My congratulations!
It was not successful me :confused:

It was simply a free by-product of the test that I ran for you.

I agree with lycorn about ECMing numbers without known factors, if ECM is what one likes to run.
