Known typos in notes:

  • Statement of 2.9.6 part (3). The statement should be replaced by "For a fixed g\in G, the number of g_1\in G such that gH=g_1H is equal to |H|", since it is then clear exactly what we are counting.


    Known typos in example sheets:

  • Question 5.12. All numberings "g_0,g_2,.....g_{p-1}" should be replaced by "g_0,g_1,.....g_{p-1}".
