Cohomology of the Mod 2 Steenrod algebra
Description
In this repo you will find the charts of the cohomology of the Mod 2 Steenrod algebra up to total degree of 261 in many formats, including pdf, sqlite3 database and csv files. You can also find an interactive plot of the E2 page of the Adams spectral sequence on https://waynelin92.github.io/ss/index.html.
In csv files, "1,2,3,4;7,8" stands for $x_1^2x_3^4+x_7^8$ where $x_i$ is the i'th generator in the generator csv table which might be given other names. That is all you need to read the csv tables. Everything else is self-explanatory.
The sqlite3 database file is the same as the csv files. sqlite3 is very easy to learn and use and is supported by most programming languages.
On the interactive plot, you can scroll the mouse wheel and drag to navigate. You can double click the dots to see the details of the elements including many of its multiples.
