      Sorry for the trouble, Jens, but I just found a slightly larger AP4:

      It was my birthday present, from Poisson.

        After deep sieving I have (100 +/- sqrt(100)) percent
        faith in Poisson.

        In this case my sieve was crude, so I give myself
        3 standard deviations and profess 70% faith.
