Hi,
Could you explain this to me ?
I am factoring Fermat numbers with ECM.
Is this relevant in this case ?
Thanks in advance,
Yann

As long as the coefficients of the curve and the starting point are
recorded, we can re-run exactly the same computation, with the small
primes
curtailed as in the p-1 case, on the same curve and the number c. It's
because my software doesn't normally output the curve and starting point
used that the idea hadn't occurred to me.
