Hello all,
I have been given a problem where I am asked to calculate "all" the components of the Riemann tensor in a gross non-diagonalized metric. I know there exists at most 20 independent components of Riemann, but I want to actually compose a list of these combinations.
It is easy enough to generate a good quantity of combinations which don't vanish under the antisymmetric exchange, but it is a bit harder to do this and account for the first Bianchi Identity. I made a list of 21 components which I should have to calculate and their could exist more but I realized I have no idea how to figure out how many more I need since there may be redundancies in my current list.
To reiterate; I was wondering if there was a compiled list somewhere for 20 independent components.
Thanks

PS: If anyone could help me to figure out what the difference in the # of components with the Bianchi Identity applied and with just the block identity//antisymmetry of the Riemann that would be much appreciated.
