19 第六章 1. 6阶群, 可能含2阶, 3阶, 6阶循环子群 存在6阶循环子群不符合题目要求
设存在{e, a, a2}, 若还存在{e, b, b2}, 则ba, ba2也存在, 超过6阶 所以3阶循环子群仅有1个 若只有2阶循环子群, 设有{e, a}, {e, b}, {e,c} 则ab, ac, bc均为新元素, 超过6阶,所以这种情况不可能.

20 e a a2 b ab a2b 3类: {e}, {a, a2}, {b, ab, a2b} 子群: {e, a, a2}, {e, b}, {e, ab}, {e, a2b}, {e}, {e, a, a2, b, ab, a2b}

21 2. D3群的对称操作分3类, 所以有3个不可约表示 E 2C3 3C2 A1 1 A2 -1 2

22 C2h群的对称操作分4类, 所以有4个不可约表示 E C2 σh i Ag 1 Au -1 Bg Bu
