Late yesterday, I found my (to-date) largest Leyland prime: 33845^26604+26604^33845. At 149763 decimal digits, this becomes for the moment the fifth largest known such prime:
386434 (328574,15) Sergey Batalov May 2014
300337 (314738,9) Anatoly Selevich Feb 2011
265999 (255426,11) Sergey Batalov May 2014
223463 (234178,9) Anatoly Selevich Jul 2011
149763 (33845,26604) Hans Havermann Sep 2020
The number is the 167th new Leyland prime discovered since I (using xyyxsieve and pfgw) started finding them two months ago. Prior to that I had found 579 new Leyland primes using Mathematica — but that took from 3 October 2015 to 3 July 2020. At my current rate of discovery, I will find my 1000th new Leyland prime on December 9, but that is likely early because I am entering large-number terrain where my finds will be slower in coming. Still, I might have it by the end of the calendar year. We'll see.
