The second-named author recently suggested identifying the generating matrices of a digital (t,m,s)-net over the finite field ${}_q$ with an s × m matrix C over ${}_{q^m}$. More exactly, the entries of C are determined by interpreting the rows of the generating matrices as elements of ${}_{q^m}$. This paper introduces so-called Vandermonde nets, which correspond to Vandermonde-type matrices C, and discusses the quality parameter and the discrepancy of such nets. The methods that have been successfully used for the investigation...
