In a recent paper I
gave polynomial expressions to compute the beginning coefficients of the
minimal polynomials for the Gauss periods and cyclotomic units lying in the
cyclotomic field Q(ξm), where ξm is a fixed m-root of unity for a prime
m. Here I extend these results for circular numbers lying in Q(ξm) for m
composite. My methods explain the linear recursion relations found among the
beginning coefficients of the minimal polynomials for certain such circular
numbers.
