      But I got there, thanks to OpenLenstra:

      I'm not confident about proving gigantic unique Lehmer PPRs like these

        Congrats! That size of 15537 digits is nearly 25% bigger than the next 12 on that "Top-20" Lehmer Primitive Part list, which all date from more than 3 years ago. So, a massive improvement!
