In the appendix B of Goldstein's classical mechanics (3rd edition), the authors discussed the dihedral group and said: "Notice how the group elements in class 3 involve only \sigma_1 and \sigma_3. Thus, they are independent of the matrices I and \sigma_2, as is expected from the structure of...

In logical implication (p implies q), if p is false, then no matter q is true or false, p implies q is true. But I think the negative of "p implies q" is "p implies not q", if so, if p is false, both "p implies q" and its negative are true, which is not possible. So is the negative of "p implies...
