Hi.(adsbygoogle = window.adsbygoogle || []).push({});

Need help with following problem:

Let R=(V,E) a regular graph with degree at least 1 and odd number of vertices.

Let C=Aut(R) the transitive action on the set E of R.

Prove C also transitive action on the set V of R.

Anyone got any idea/tips?

Thanks!
