I had taken some intro level academic courses in Combinatorics and Abstract Algebra. Sadly, my university doesn't allow to undergrads to partake in the more advance courses, or only at the very end of the bachelors.
Therefore, I'd be thankful to get some recommendations for any comprehensive books in the study fields mentioned above.
I'd heard some good things about Abstract Algebra by Dummit and Foote, but I don't have enough knowledge to compare them to others.
