I really like SymPy and support the hard working developers constantly improving it. This software is incredably complex and really needed. One day it will be a viable open source alternative for Matlab and Mathematica. That said, for my specific use case (modulo arithmetic / cyclic groups) I didn't get SymPy to work properly. While I was able to find guidelines on how to hack it together, I have not found a real solution. After 2 hrs of search, I retreated in shame to Mathematica. If anyone knows a solution or works with these structures, let me know!
