Properties of the combinatorial Hantzsche-Wendt groups
Combinatorial Hantzsche-Wendt groups G(n) were defined by W. Craig and P. A. Linnell. For n = 2 it is a fundamental group of 3-dimensional oriented flat manifold with no cyclic holonomy group. We calculate the Hilbert-Poincare series of G(n), n > 0 with Q and F2 coefficients. Moreover, we prove that a cohomological dimension of G(n) is equal to n + 1. Some other properties of this group are also considered.
