Abstract

UDC 517.9

We find periodic solutions of the Coulomb equations of motion for three equal negative point charges in the field of six equal positive point charges fixed at the  vertices of a octahedron.  The system possesses an equilibrium configuration.  The center Lyapunov  theorem is applied.
