# Thread: Construct an abelian group

1. ## Construct an abelian group

Hey
For any n>2 construct a non-abelian group of order 2n. How do I go about this?

Any help will be appreciated

2. It may be of use to know $D_{2n}\cong \mathbb{Z}_n \rtimes_\phi \mathbb{Z}_2$. Since they tell you to construct it, but I don't know.
