Applied Discrete Structures by Al Doerr and Ken Levasseur, both from the UML Department of Mathematical Sciences, has reached two significant milestones:

- The book is now listed as part of the American Math Institute’sOpen Textbook Initiative.
- It has its first outside adoptions: classes at the University of the Puget Sound, Grinnell College, Casper College and Luzurne Community College are all using the book in the spring of 2013.

Resources, such as this dynamic demonstration of cyclic subgroups of the group of integers mod n are continuing to be developed. Move the sliders to see the different subgroups with varyingmoduli:
