Let K be the splitting field of x^n - 17.
                                                                                
Show that G(K/Q(有理數)) is isomorphic to
                                                                                
{(i  j)   |i beling to Z_n^*, j belongs to Z_n}
  (0 1)
                                                                                
(i   j)
(0 1) 是指2X2的矩陣。
                                                                                
這題完全不知道要如何下手,請高手們幫忙一下,感激不盡。
