Speaking about primo proofs:
I have a few (4 + 2) candidates of irregular and Euler irregular primes waiting for a primo primality proof. They are ranging from about 22000 to 29000 digits, but are far beyond my current computing resources. If one of you is (seriously) interested, please drop me a note.

Should one think that Peter immediately rushes to Wikipedia to update his record for posterity after finding a record? I am sure that he has other better things to do. Or maybe someone else does for him? Also probably not. There is a reason why even school teachers don't give children a grade for a quote from Wiki. Wiki is broadly correct in generalities, and overwhelmingly incorrect in expert details. The algorithm for searching for facts is: start with a general blurp from Wikipedia, continue searching using links and links from links... then you might build some semblance of a current state of the art.
