An [URL="http://gladhoboexpress.blogspot.com/2020/03/my-500th-leyland-prime-find.html"]update[/URL] 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 [URL="http://gladhoboexpress.blogspot.com/2020/04/half-way.html"]upper-half of interval #14 search[/URL]. Click the link if you are curious to see what this looks like on the three Mac minis that are running the calculation.

[QUOTE=pxp;538161]That makes L(40089,82) #1496.[/QUOTE]

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.
