Dear Furcan, The topic is very interesting, there are several implementations of "symmetry analysis of differential equations" in software, for example, see Gerd Baumann "Symmetry Analysis of Differential Equations with Mathematica", or the project jets.math.slu.cz (I did not know about the book by Hans Stephani, thank you). Of course, it would be interesting to do similar things in SAGE, and I could also contribute a bit to this project :)
