GR_CASprzak is an extension of CASprzak whose goal is to automate many of the very long computations found in General Relativity/Tensor Calculus
Hello, and welcome to GR_CAS. When I was learning GR, I reached a point where I needed to calculate 256-term Christoffel Connections and Curvature Tensors and I didn't have a Mathematica license to do it the normal way. So instead I wrote this as an extension of a Computer Algebra System I am working on.
