This textbook is one half of an interactive course from Colorado State University. The other half of the course consists of 47 videos that are also freely available on the CSU YouTube channel. The text has convenient links to the videos so that it is easy to find the video matching the topic. The text and videos have now been used for a number of years in their one-semester introductory combinatorics course that also includes some graph theory. It can also reasonably be used in a strictly combinatorics course on a quarter calendar by covering chapters 1-7.
Most chapters contain an investigative section that goes more deeply into a topic. There are several examples throughout the book that use Sage with the twin goals of introducing Sage and of solving problems that are impractical to do by hand.
