Largest Leyland Prime Hunt
In fact, I found two new primes in that interval:

I'm done. In addition to Anatoly Selevich's L(314738,9), I found 16 new primes. The two-and-a-half months was pretty close. So to get up to 305000 decimal digits (which is on my schedule) will take...

I have examined all Leyland numbers in the two gaps between L(49413,580) <136550>, #2485, and L(49878,755) <143547> and found 123 new primes. That makes L(49878,755) #2610 and advances the index to...
