RE: Please Review a Diffie Hellman diagram

Actually, the values you picked worked fine. 5 is indeed a primitive
root of 7 (or "generator" of 7 using Sanjay's terms). As long as Xa < T
and Xb < T, you're fine.

Thanks for all the great feedback. I am working to improve the diagram
:-)

A lot of people email me asking to select R and T, Xa and Xb such that:
Ya != Xb and Yb != Xa.

Any suggestions for the value of R, T, and Xa and Xb . I would like to
keep the number small enough for people to do the calculation without
the use of a electronic device. Remember I am creating this for high
school students.
