I'm trying to reproduce the results of this paper where the author calculates the Ricci rotation and spin coefficients with Mathematica, when provided a metric and a choice of tetrads. I looked through the literature and references of SageMath and I couldn't find any mention of tetrad methods.
I came across this post in this forum from 3 years ago where the answer mentions that general tetrads are implemented but spin coefficient methods are not. It links to the documentation page with a lot of info and since I'm a total beginner in SageMath, I'm finding it very difficult to understand what needs to be done. Can anyone help me with how to do this or maybe refer me to a notebook example where this is done? Please let me know. Thanks.
