Several mathematical results and new computational methods are presented for primitive elements and their minimal polynomials of algebraic extension fields. For a field Q(@a"1,...,@a"t) obtained by adjoining algebraic numbers @a"1,...@a"t to the rational number field Q, it is shown that there exists at least one vector =(s"1,...,s"t) of integers in a specially selected set of (-1)N vectors such that s"1@a"1+s"2@a"2+...+s"t@a"t is a primitive element, where N is the degree of Q(@a"1,...,@a"t) over Q. Furthermore, a method is presented for directly calculating such a vector, that gives a primitive element. Finally, for a given polynomial f over Q, a new method is presented for computing a primitive element of the splitting field of f and its minimal polynomial over Q.
