Hi

I was playing around with the client program.
When I go to the advanced menu and choose ecm, there I fill in for exponent 101 and 
check the factor 2^N-1 box and click ok.
After about a minute the program says to me :

Stage 1 complete. 25964568 transforms, 1 modular inverse. Time: 59.738 sec. 
(27838040173 clocks)
P101 has a factor: 3
Cofactor is a probable prime!

If my calculations are correct 2^101-1 = 2535301200456458802993406410751
To check if this is divisible by 3 add al digits and check if the sum is divisible by 3
Total of digits is 112 so 3 is not a factor.

Is this a bug in the client? or do i make an error somewhere?

Regards,
 Jeroen
