Review for NeurIPS paper: MDP Homomorphic Networks: Group Symmetries in Reinforcement Learning

Additional Feedback: In the caption of figure 4 (b) I believe CNNs should be MLPs. In Figure captions it says that 25% 50% and 75% quantiles are shown but I only see one set of error bars. Line 142: Equation 9 should be Equation 8? Line 155: should this really be for all g given you are talking about a specific s \prime and a \prime? Is invertibility an assumption here? I can't immediately see why it should need to be so.
