      Aldrich, I have to say that your description of Prof. Caldwell's
      solution - "opus delectus" and "hideously beautiful" - had me
      laughing. Helped to cheer my day, thank you.

      Like you, I have little idea about how Mr. Caldwell did what he did.
      But I'm pretty sure that, if you retain the order of the numbers as
      you presented them, you won't be able to generate those numbers with a
      (one variable) polynomial of any order under about 90.

      Why? For instance, look at the first 9 numbers you started with:

      3167 2753 2753 1979 2357 1277 1979 647 1619.

      I remember drawing smooth line graphs a very long time ago in grade
      twelve (?) calculus, and doing the minima and maxima thing. Derivative
      (or slope) equals zero at the minima and maxima. Generally speaking,
      and if I recall correctly, a polynomial of degree two had one minima
      or maxima (valleys or peaks), a poly of degree three had two valleys
      or peaks, and so on. If you were to graph just the nine numbers above
      with a smooth line you would see a very curvy line with seven peaks
      and valleys. So, these first nine numbers alone would require a
      polynominal of at least degree eight if I'm not mistaken.

      So I think your "little procedure" for prime generation from a given
      set of seed primes is proving much easier and interesting and fruitful
      than the polynomial route. (Not that I inspected your procedure very
      closely.) Mum would be proud. :)
