| Abstract: | The continuing and widespread use of lattice rules for high-dimensional numerical quadrature is driving the development of
a rich and detailed theory. Part of this theory is devoted to computer searches for rules, appropriate to particular situations.
In some applications, one is interested in obtaining the (lattice) rank of a lattice rule Q(Λ) directly from the elements
of a generator matrix B (possibly in upper triangular lattice form) of the corresponding dual lattice Λ⊥. We treat this problem in detail, demonstrating the connections between this (lattice) rank and the conventional matrix rank
deficiency of modulo p versions of B.
