WebTo describe cyclotomic extensions, we need to use the Euler phi function. If n is a positive integer, let ¢(n) be the number of integers between 1 and n that are relatively prime to n. The problems below give the main properties of the Euler phi function. We also need to know about the group of units WebFor example, square roots of integers are cyclotomic integers (see ATLAS irrationalities), any root of unity is a cyclotomic integer, character values are always cyclotomic integers, but all rationals which are not integers are not cyclotomic integers. gap> r:= ER( 5 ); # The square root of 5 is a cyclotomic integer. http://math.colgate.edu/~integers/current.html can girl chickens crow
