The photo shows four recently acquired Mac minis that were meant to complement my previously-existing Leyland prime search farm. The "silver" one is the new M1 Mac mini and I did not find it suitable for the task, so it is not part of the farm. The other three are Intel and add 18 cores to the previous 54, for a total of 72 cores. This will help with my current work on interval #18 which is checking for the probable primality of 1087659 terms ranging in size from 111532 to 121787 decimal digits. My updated-in-real-time search results are posted on my indexing the Leyland primes document.
