Query: Schellbach-style Formulae for the Derousseau-Pampuch Generalizations of
  the Malfatti Circles   It is known that there exist 32 triplets of circles such that each circle is
tangent to the other two circles and to two of the sides of the triangle or
their extensions. We provide formulae to obtain the radii of the circles for
each of the 32 triplets from the side lengths of the reference triangle by
means of trigonometric or hyperbolic functions.
