      Mike Oakes visited me and we attended a conference on
      general relativity and cosmology. It seems that this
      coincided with the discovery of a local region of high
      curvature, in probability space. There are clearly a good
      few AP3s that can be found by taking two elements from the
      PrimeGrid SG/Twin survey, but finding 4 in the space
      of a couple of days was unexpectedly non-Euclidean.

      It seems to me that PrimeGrid is already slightly unlucky
      not to have found an SG or Twin pair by now?

        No longer able to congratulate you over the cornflakes, but anyway: many congrats on another hit.

        My slight concern is: how long before all the rest of us are knocked off both tables of this page:
        http://primes.utm.edu/top20/page.php?id=14
        leaving only who=p199?

          I think that PrimeMogul protects you, by allowing
          no more than 5 AP3s as "listable" in those tables.

            Take heart: Ken and I and the e-group are trying to top the second table. I am about 18 of 35 GHz years of PRP'ing, scheduled to finish by July, with hopefully a few months extra real time of detection. Ken is concurrently searching for an titanic AP9 now. In the eventuality, the puny numbers found by us will outdo David and the mighty PrimeGrid.

            The lowest ranked doubly beastly exponent is ranked 4481; PrimeGrid can find another 519 of these before they start to eat their own tail.

            Good luck to PrimeGrid with SGs/twins and also to David finding more AP3s,
