Well, it doesn't really impact on the WEP-M+2 project, which is still
testing the WEP algorithm, without yet, any conclusive results either
way.
This factor was found (by me) using the Elliptic Curve Method, and is
of interest as a new factor (of a reasonable size too) in the general
search for factors in the M+2 project.
