After hearing my podcast with Amie Wilkinson, someone asked me about books they could use to teach themselves group theory or abstract algebra. I recommended Nathan Carter‘s book “Visual group theory“ and Charles Pinter’s “A book of abstract algebra”. Other suggestions?— Steven Strogatz (@stevenstrogatz) May 10, 2021
Don't know the books, or group theory for that matter. But Strogatz is sharp so I take his advice seriously.
