This GAP package computes cohomology rings for finite p-groups using Jon Carlson's method, both as GAP objects, and also in terms of generators and relators. It also computes induced homomorphisms on cohomology and Massey products in the cohomology ring.
The latest version of this package is normally bundled with GAP, so it should not be necessary to manually install it. However, if needed, you can always download the latest version from https://gap-packages.github.io/crime/
Please refer to the package documentation for more information.
