Symmetry-finding with SAGE?

I have prepared algorithm in SageMath which finds determining equations for infinitesimals of ODE of order 2 and 3. My paper is published on this with title "Determining equations for infinitesimal transformation of second and third-order ODE using algorithm in open-source SageMath" in Malaya Journal of Matematik.
