Combinatorics. A very short introduction (Q2790307)

The book provides an introduction to the main topics in combinatorics by providing a lot of examples and covering the most famous and well known problems. So, the author discusses topics such as the Königsberg bridges problem, the four color problem, Latin squares and provides a short introduction to permutation and combinations, graph theory, block designs and finite projective planes. The focus is often on examples and the book offers a view of these topics in such a way that the non-expert reader might understand them. So the author shows applications of these ideas and introduces the reader to the way of reasoning in this type of results and also to the history of this subject.
