Abstract: Let be any totally complex quartic field. Two algorithms are described for determining whether or not any given ideal in is principal. One of these algorithms is very efficient in practice, but its complexity is difficult to analyze; the other algorithm is computationally more elaborate but, in this case, a complexity analysis can be provided.

These ideas are applied to the problem of determining the cyclotomic numbers of order 5 for a prime . Given any quadratic (or quintic) nonresidue of *p*, it is shown that these cyclotomic numbers can be efficiently computed in binary operations.
