You are correct! I am a bit delayed on the official announcement due to having knee surgery a few days ago, but I should have it up in the next day or so.



____________
141941*2^4299438-1 is prime!

This one takes over 1st place on the weighted list (bumping
my k = 329 to 2nd). Subsequent Fermat Divisors found during
our march to n = 1M will also enter as 1st on the weighted list.
