子群的陪集 Let G be a group and H a subgroup of G.Define a left coset of H with representative g EG to be the set gH={gh hEH Right cosets can be defined similarly by Hg={hg:hEH. Example 1.Let H be the subgroup of Z6 consisting of the elements 0 and 3.The cosets are 0+H=3+H={0,3} 1+H=4+H={1,4 2+H=5+H={2,5}.子群的陪集
