Four equal masses attracting each other with the classical gravitational force can
   perform a "choreography" known as Gerver's Supereight and shown in the following
   movie:

SuperEight.avi

   This Supereight choreography for 4 equal masses can be continued in several ways,
   as is illustrated by the following sequences of movies:

• Continuation under a change of the potential


• Continuation under a change of the masses m1=m3=m


• Continuation under a change of the mass m2=mu


• Continuation under a change of the masses m1=m4=m

   Exploring these solutions one finds 4 different orbits for the case of 4 equal masses.

   The orbits shown in these movies were computed by
   Francisco Javier Muñoz Almaraz (Universidad Cardenal Herrera, Valencia)
