**Known typos in the book ***Groups* by Jordan and Jordan:

None reported yet.

**Known typos in the lecture notes:**

Page 22, line 4. "equivalence relations" should be "equivalence classes".
Page 31, line 7. "edge connecting f(v_1) and f(v_2)" should be "edge connecting g(v_1) and g(v_2)".
Exercise 2.7. The question should ask "Find a non-trivial symmetry f..." instead of "Find a symmetry f...", since the identity commutes with all elements, but this is not the point of the question!
