      Dr. David Broadhurst of Open University U.K, graciously
      declining the $91.91 prize, has satisfied the requirement
      with the following contiguous remarks:

      "Tell your mum to download Pari-GP:

      http://pari.math.u-bordeaux.fr/download.html

      Then tell her that your vector of 91 primes is

      mum=abs(vector(91,x,if(x%2,
      (9*x^2-864*x+13523)/4,9*x^2-441*x+3599)))

      which you obtained by using absolute values of different
      transforms of the Fung and Ruby quadratic for even and odd
      values of x.

      If you want to show her Chris Caldwell's /unique/ polynomial
      p(x) of degree 90 such that p(x)=mum[x] for x=1..91, simply
      tell her to type

      polinterpolate(mum)

      to obtain the polynomial in the attached file "mumpoly.txt"."


      Mum is happy and so am I.

      Aldrich
