The <Lagrange, Euler, and Kovalevskaya tops> are three integrable cases of fixed-point <rigid body dynamics>. The Euler top has no external torque; the Lagrange top has axial symmetry and its center of mass on the symmetry axis; the Kovalevskaya top has two equal principal moments twice the third and its center of mass in the corresponding principal plane.
