I added the spkg to experimental right off, so people can just do sage -i p_group_cohomology-1.0 It would be very useful if you could post on the ticket *PRECISELY* what you think a person should do to referee it and sign off on it being officially added to the optional package repo. I.e., 1. Install on the following hardware/OS combos as follows. 2. Run the following commands (and here is what should happen). 3. Look in the spkg and read the following, checking for ...: Whether or not the referee will agree that this is enough testing is up to them. However, it will be tremendously helpful to get them going. > Let me draw your attention to the fact that with this package we were > able to compute the cohomology rings for all groups of order 128 and > for all but six groups of order 243.
