Tóm tắt

Determining the possible values of integer circulant determinants is an open problem proposed by Taussky-Todd. Recent interest in this question comes from studying the Lehmer constant of finite cyclic groups. By refining the approach by Laquer and Newman we contribute to the circulant determinant problem in the case that the order is a power of two.
