The 59k+ digits Leyland prime

3^125330 + 125330^3

was proven prime via ECPP in mid December by Greg Childers, which, to my knowledge, makes it the largest prime proven via ECPP. However, so far it hasn't been included in the ECPP list at prime.utm.edu. Does anyone know the reason? The certificate is uploaded and verified to/by factordb.

There have been a few recent ECPP numbers not making their respective top20 tables. I told Prof Caldwell. I guess he is busy retiring. Perhaps someone can email him about these numbers.

I sent an email a couple of weeks ago but haven't gotten a reply. I just chalked it up to some combination of retiring and the holidays.

For many people, retirement is the busiest age of their lives.
