G001 — Z_n與proper雙邊理想的全部加法cosets。操作=quotring-classes;資料={"n":8,"d":4}。請依 [ideal,cosets,quotient_size,certificate] 欄序回答。沿用原題明示的論域、假設與來源 MKO 定義。本題已完成第二對話數理與中英語義覆核,並由原始參數逐題獨立重算模型、答案與每個算術步驟;原題仍為 candidate。

操作前
same declared parent Z_8;generator d=4;n/d=2;ideal multiples=[0, 4]
操作後

條件:無
因d整除n,整數代表改加n仍不改mod d,π:Z_n→Z_d良定且保加乘。核I由d倍數組成,加法差封閉且左右乘任意母環元素仍在I。d≥2使1不在I,故proper;d=n可得零理想,不把它排除。
