5,433+ factored
5,433+ has been factored into 133-digit and 139-digit prime factors. This sets a second place record for SNFS difficulty and a first place record for largest penultimate factor for the Cunningham project! The sieving of 2,1061- is going well using the new app for 64-bit Linux, as is the sieving of 10,305+ and 2,1019- using the traditional apps. 11,290+ is in postprocessing and should finish this weekend.
