I have tools to rapidly compute ECM group orders specifically for
Richard Crandall's ECM curve parameterization you use. Just send
me a list (or .txt attachment) containing any (prime factor, sigma)
pairs you are interested in.

38917 is required and during stage 2 the block of
primes for B2 >= 534241 happens to include the largest factor 535489.

running my laptop 24/7 like a desktop. The fan unit slid into
and was powered by the lower of my two PCMCIA slots. While running
Prime95 with the fan running the case was barely warm to the touch.
These PCMCIA fans used to cost around $35 from Micro Center or CompUSA.

Hi Jeroen
According to the Cunningham tables:
2^101-1 = 7432339208719 * 341117531003194129
2^101+1 = 3 * 845100400152152934331135470251
Are you sure you did not select the "+1" option by mistake ?

I find it quite invaluable in investigating these type of situations. You can
fire it up in a few second to investigate some anomalous behaviour or leave it
running in the background continuously where it consumes about 0.5%

Here is another vote for P-1 to default to off unless it
is explicitly enabled using the Advanced Menu like ECM.

As far as I know most Mersenne factoring programs use on some form
of Large Integer Package (LIP) to handle the size of numbers involved.

irst stage (carried forward to Second stage).
If not you have some kind of problem!!
If you have any other questions please contact me privately,
so we can discuss this off the Mersenne List.
