Hantzsche–Wendt manifold

The Hantzsche–Wendt manifold is a specific type of 3-manifold that serves as an example in the study of topology and geometry. It can be characterized as a compact, orientable, triangulated manifold with non-trivial fundamental group. One main feature of the Hantzsche–Wendt manifold is that it can be constructed from 3-dimensional Euclidean space and is related to the theory of solvable Lie groups.
