In this case W has a diagram with 2 vertices and one edge labelled ∞, and is therefore the infinite dihedral group. Thus W is virtually ℤ.

Another class of small manifolds consists of those that are not virtually Haken (a manifold is virtually Haken if it is finitely covered by a Haken manifold).

We call a hyperplane Y in a VH-complex X virtually clean if there exists a finite-sheeted covering map p : X̂ → X and a connected component Y ⊆ p⁻¹Y such that the hyperplane Ŷ of X̂ is clean.
