摘要

We present the point symmetry classification and invariant characterizationof a system of two geodesic equations. Previously, Aminova and Aminov attempted the point symmetry classification. However, they did not identify the Lie algebras nor did they provide an invariant characterization, in terms of coefficients, of the geodesic equations. In this paper we do both.
