definition of anti-divisor

[Jonathan Post]

Thank you Neil, for putting the cached John Perry Page where we can
get it.  Thank you Max, Diana, et al for corrections and
clarifications.

To extend, then, eliminating the "more" (though anyone is welcome to
submit mathematica or equivalent, and a b-list):

Next, the matters of iteration, fixed points, primes in A130846 can
commence, subject to Neil's taste as bounded by "less"itude.
