Enumeration of equivalence classes of finite-sheeted coverings of the Hantzsche–Wendt manifold

We enumerate the equivalence classes of finite-sheeted coverings of Hantzsche–Wendt manifold. This manifold is the most complicated of the closed flat 3-manifolds, and occurs often in low-dimensional topology. This is a joint result with A.D. Mednykh. Also we are going to give a brief overview of associated classical results, including the classification of closed flat 3-manifolds up to affine equivalence.
