Galois group in a de nite way. There are three roots of X3 2 being permuted by the Galois group (in all 6 possible ways), so if we label these roots abstractly as 1, 2, and 3 then we can see what the correspondence should be. Label 3 p 2 as 1, !3 p 2 as 2, and !2 3 p 2 as 3. Then (12) xes !2 3 p 2, and therefore Q(!2 3 p 2) is contained in the ...
