I am interested in some ongoing discussion regarding RtR. Are there
those here who are still engaged with the book or related books? I
have just finished Chap. 13, "Symmetry Groups".

My education is in engineering. The contents of the book, especially
Chap. 13, is largely material that I have either not seen or seen
briefly. Nonetheless, I am working through it since I think it is
neat. I am also using C++ and SciLab to try to model and / or further
explore some of the material.

Best regards,

Thomas
