Resolvent method
The resolvent method is just a systematic way to check groups one by one until only one group is possible. This does not mean that every group must be checked: every resolvent can cancel out many possible groups. For example, for degree five polynomials there is never need for a resolvent of D_{5}: resolvents for A_{5} and M_{20} give desired information.
(注：下記では、ラグランジュ・リゾルベントを上記の一般的なResolventに近い意味で使っている。また、代数的に解ける場合に限定している)
