Title: 2-Walk-regular graphs from group-divisible designs

Abstract:

In this talk I will give a construction for 2-walk-regular graphs coming from group-divisible designs with the dual property. I will give examples of these graphs and show infinite examples of 2-arc-transitive dihedrants. This is joint work with Shao Fei Du and Zhi Qiao.
