Query: Coordinates for a new triangular tiling of the hyperbolic plane   In this paper we define an infinite family of triangular tilings of the
hyperbolic plane defined by two parameters ranging in the natural nummbers and
we give a uniform way to define coordinates for locating the triangles of the
tiling.
