  procedure Symmetric_Set_Structure_Info;

  -- DESCRIPTION :
  --   Displays information on symmetric set structures on screen.

  -- DESCRIPTION :
  --   Interactive driver for the construction of a
  --   (G,V,W)-symmetric random product start system.

  -- ON ENTRY :
  --   file         output file to write diagnostics on;
  --   p            a polynomial system;
  --   bs           Bezout number based on the set structure;
  --   lpos         list of positions.

  -- ON RETURN :
  --   q            symmetric random linear-product start system;
  --   qsols        solutions of q;
  --   bs           Bezout number based on a symmetric set structure;
  --   lpos         list of positions for the new set structure.
