The Promotion Of The Gauss Theorem, Ideal For The Remaining Groups

By using the method of algebraic number theory, we can generate Gauss' theorem to the group of residue classes mod m and receive the following conclusion:If b is the ideal of the group of residue classes mod m , then(e(2) is the number of those basis elements whose order is divided by 2).By using the above conclusion, we can prove the following congruence:e(2) is the number of those basis elements whose order is the power of 2, h is the number of elements in
