- Computer lab on Friday, October 21. Please bring your textbook.
- There is a limited-time amnesty program for the midterm.
- Some of the material on primitive roots can be found in A Friendly Introduction to Number Theory, by Joseph Silverman.

- Midterm on Monday, October 10, in class. No notes, no calculators, no textbook; just yourself and your pen or pencil. Friday, October 7, in class would be a good time to ask questions.

- Office hours on Thursday, September 8, are 2-3.
- In Chapter 2 the textbook, when encoding letters as numbers, uses
A&rarr 0, B&rarr 1, etc. (This makes a difference for
affine ciphers, but not for shift ciphers. Why?)

Show that the equation 6x + 15y + 18z =1 has no solution in integers x, y and z.
- On Friday, September 2, we'll meet in Weber 205 for the first computer lab. Please bring your copy of the textbook.
