I have just recently ported the regular case as well to Mathematica. I did not port this directly from SLIEGN2, but rather used NDSolve with the differential equations derived from Prufer Coordinates. I'm familiar and have used SLEIGN2 as well. I am interested in porting this to Mathematica. I'd enjoy some collaboration, if you have time. I am a graduate student with experience in programming. But not so much with Mathematica. One question I do have - is what is your interest in using Mathematica to solve SL problems??
