| Abstract | Second and third order differential equations invariant under two different realizations of S L(2,R) are discretized in a manner preserving their Lie point symmetries. The symmetry preserving discretizations are used to obtain numerical solutions. These discretizations (contrary to the standard ones) provide solutions that are valid close to singularities and beyond them.
