An update on my ongoing prime search. The bad news is that I am not likely (as previously hoped) to finish by this time next year.

I am now past the six-month mark of my upper-half of interval #14 search. Click the link if you are curious to see what this looks like on the three Mac minis that are running the calculation.

I have examined all Leyland numbers in the seven gaps between L(40089,82) <76723>, #1496, and L(32160,329) <80954> and found 62 new primes. That makes L(32160,329) #1565.

My Leyland prime indexing page has a new Google Drive backup URL.
