It's still in beta (alpha?) testing.

You've not been lucky...
When you find a factor, the server answers "Factor found : xxxxxxx" before loading the startpage.

P.S. I noticed that someone has already discovered a more-than-57-bit factor!
P.P.S. Maybe I'll have to insert some new exponent to the queue...

hmmm pm1 would have been a better method there
Written in php, with less than 50 lines of code, and running in batches of 3-4 seconds? I doubt it...

Is this a machine that you have full time control over? Or have you figure out a way to get time on this machine by doing "fancy webpages"?

Suggestion:
Add a button to the right of the stats that says something like "Test a 'Random' number from the list".
Have it find the number with the lowest 'k' that has no known factor and test it.

What is the significance of the range?

mfaktc can only test TF up to 2^32-1. After, you have to use either factor5 (which is much slower) or use ET_ applet, which doesn't move fast either,but can help you relieve your boredoom, as each test take 4 or 5 seconds.
an other reason could be to see how evolve k in that range , its distribution... or will edington interest in 'large' mersenne factor. Or, even less probable, just a challenge in PHP, and revelant to the interest of ET?

That's a good point, especially when the list grows up!
I hope I can add it next Friday.

All your guesses are exact...

Default are factors shown incorrectly ?

factors in the exponent table are not equal to 2kp+1. Am I wrongly interpreting your table ? For instance in the second row:
for P=4294967357 you list K=35000535 and Factor=34359738857,
but if I am not mistaken, this factor gives a k value of 4.
Can you tell me where I am wrong?

For the bit depth of factors you should check here

The exponents table shows how deep each exponent has been trial-factored.
