If you see any errors or have any questions, I can usually be found in Discord.
Note: To print the matrix, use Google Chrome and highlight (select) only what you want to print. Right-click and click print. Google Chrome will send only the highlighted selection to the printer by default. Full matrix with footnotes will fit on two pages.
