Показать описание
We have reviewed basic facts on cyclic groups and then studied the number of generators of a cyclic group with n elements. We also found the generators of Z/8Z and the subgroups of Z/12Z.
We then moved to prove Fermat's and Euler's theorem.
We introduced normal subgroups and saw basic examples.
