Найдено 50 наборов значений констант межчастичного взаимодействия в задаче четырех тел в плоскости, при которых компоненты общего решения являются мероморфными функциями, а также 15 наборов, при которых соответствующие им системы имеют решения с подвижными критическими особенностями. Полученные результаты могут быть применены в аналитической теории дифференциальных уравнений, а также для решения ряда задач космической динамики. </p></abstract><trans-abstract xml:lang="en"><p>The purpose of the study is to establish the analytical properties of solutions of nonlinear differential equations describing the planar motion of four bodies. 50 sets of constant values of interparticle interactions in the problem of four bodies in the plane are found, at which the components of the general solution are the meromorphic functions, as well as 15 sets, at which the corresponding systems have no Painlevé property. The results obtained can be applied in the analytic theory of differential equations, as well as for solving the problems of cosmic dynamics. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>движение четырех тел</kwd><kwd>константа взаимодействия</kwd><kwd>подвижные критические особенности</kwd><kwd>мероморфное решение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>motion of four bodies</kwd><kwd>the constant interaction</kwd><kwd>Painleve property</kwd><kwd>meromorphic solution</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Calogero, F.
