Cohomology of 2-Groups

Pierre Guillot

This project about the cohomology of 2-groups has information about Stiefel-Whitney classes and Steenrod operations. Most of the computations were in C++ but Sage has also been crucially used (how else could you call GAP, mathematically process the information, download stuff from Carlson's page, call the C ++ programs, and then produce the HTML files, all in one language?)
