The most convenient way to report a typo should reference the file and line number where the typo occurs:

• Find the file in the content tree: https://github.com/OpenLogicProject/OpenLogic/tree/master/content
• Click on the line number; then on the menu indicated by three horizontal dots
• Select "Copy permalink" and paste that link below.

Alternatively describe the location of the typo (page #, "after Theorem 5.1", etc., and mention which PDF you are referencing)

Typo location: https://github.com/OpenLogicProject/OpenLogic/blob/d4e99d08a596c627e4f3a922b94dd74f0932b1cb/content/sets-functions-relations/sets/basics.tex#L75
