  Following recent developments in discrete gravity, we study geometrical
variables (angles and forms) of simplices in the discrete geometry point of
view. Some of our relatively new results include: new ways of writing a set of
simplices using vectorial (differential form) and coordinate-free pictures, and
a consistent procedure to couple particles of space, together with a method to
calculate the degrees of freedom of the system of 'quanta' of space in the
classical framework.
