Combinatorics

A mathematical gem–freshly cleaned and polished

This book is intended to be used as the text for a first course in combinatorics. the text has been shaped by two goals, namely, to make complex mathematics accessible to students with a wide range of abilities, interests, and motivations; and to create a pedagogical tool, useful to the broad spectrum of instructors who bring a variety of perspectives and expectations to such a course.

Features retained from the first edition: *Lively and engaging writing style *Timely and appropriate examples *Numerous well-chosen exercises *Flexible modular format *Optional sections and appendices

Highlights of Second Edition enhancements: *Smoothed and polished exposition, with a sharpened focus on key ideas *Expanded discussion of linear codes *New optional section on algorithms *Greatly expanded hints and answers section *Many new exercises and examples
