Permutations are omnipresent in modern combinatorics--omnipresent but also multifaceted. While several other books explore particular aspects of the subject, no one book has covered them all, and even the classic results are scattered in various resources. Winner of a CHOICE Outstanding Academic Title Award for 2006, Combinatorics of Permutations offers a comprehensive treatment of both enumerative and extremal combinatorics. The author's style is relaxed and clearly reflects his enthusiasm for the "serious fun" the subject holds. Filled with applications and exercises that draw upon recent results, this book serves equally well as a graduate-level text and a reference for combinatorics researchers.
