Sure it's simple. Factorization is not my field of expertise, but I would be surprized if trial division would not already be part of the factorization routines (but perhaps with a too small base). Concerning Cunningham: There has been a thread on Sage devel (http:// groups.google.com/group/sage-devel/browse_thread/thread/ 6d2ef34de1a5eb27/87db0305f9022ff3) and two trac tickets #7239 and #7240 (that's to say http://trac.sagemath.org/sage_trac/ticket/7239 and http://trac.sagemath.org/sage_trac/ticket/7240 ) concerning factorization of Cunningham numbers. The first ticket is already part of Sage, but the second needs work and hasn't been touched since a while. > That is worth lost 5 second on the start ... Do you mean by "5 seconds on the start": The time that Sage needs to start up would increase by 5 seconds? I think many people would think that the startup time of Sage is already too much, so, increasing it further wouldn't be good.
