A system describing the motion of four bodies under the action of gravity is considered. By elementary algebraic manipulations a simple system consisting of non-linear differential equations, each of which has a second order is selected. For each simplified system there are sets of constants of interparticle interaction, in which the general solution is meromorphic.
Keywords: movement of four bodies, meromorphic function.
Mots-clés : constant interaction, Painlevé property
