2nd ed. — Dover Publications, 1994. — 234 p.A stimulating excursion into pure mathematics aimed at "the mathematically traumatized," but great fun for mathematical hobbyists and serious mathematicians as well. Requiring only high school algebra as mathematical background, the book leads the reader from simple graphs through planar graphs, Euler's formula, Platonic graphs, coloring, the genus of a graph, Euler walks, Hamilton walks, and a discussion of The Seven Bridges of Konigsberg. Exercises are included at the end of each chapter. This Dover edition, ﬁrst published in 1993, is a slightly corrected, enlarged republication of the work ﬁrst published by The Kent State University Press, Kent, Ohio, 1976. For this edition the author has added a new section, “Solutions to Selected Exercises,” and corrected a few typographical and graphical errors.Preface. Pure mathematics. Graphs. Planar graphs. Euler's formula. Platonic graphs. Coloring. The genus of a graph. Afterward. Solutions to selected exercises. Index. Special symbols.
