      I do not find a method to construct P*U, but there are simple loci (ie we
      can find them by simple computations)
      for P if U is fixed. For example:

      ---- which is the locus of P such that Q, P, P*U are collinear?

      --- which is the locus of P such that the line PP*U is parallel to Euler
      line?
