Hello Big Minds,
In the following analysis...It is said that D_2 contains three subgroups Z_2...why did he choose a mathematical constuction contains only two of the the three subgroups? shouldn't he use the three in his construction? what will happen if he used the three?
[from the book of P.Ramond, Group Theory, p8.]
best regards
