      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,

          I shall issue a retraction by King Lear
          when that notable feat is accomplished,
          as now seems more or less assured.
