 note = {We considre possibility of constructing symplectic integrators with arbitrary degree of precision which share invariants of motion with original Hamiltonian flow. It is shown that those integrators obtainable by the method due to Neri can preserve the same Noether invariant as the original Hamiltonian flow when kinetic and potential parts of the Hamiltonian possess a symmetry in common.},
