A Book Of Abstract Algebra Pinter Solutions -

Prove that the set S = ε, (12)(34), (13)(24), (14)(23) is a subgroup of A₄.

Most universities use abstract algebra as a weeder course for math majors. Pinter flips this script. He begins with a "User’s Manual" for the field, explaining the game of algebra before the rules. He introduces concepts like groups, rings, and fields with historical context (Galois, Lagrange) that makes the math feel alive. a book of abstract algebra pinter solutions

Officially, Dover does not publish a full solutions manual for Pinter. Why? Because abstract algebra is not about getting the right answer; it is about the justification . However, a partial answer key exists in the back of the book for odd-numbered exercises. This is your starting point. Prove that the set S = ε, (12)(34),
