**Abstract:**
A vertex triple \((u,v,w)\) of a graph is called a \(2\)-geodesic if \(v\) is adjacent to both \(u\) and \(w\)
and \(u\) is not adjacent to \(w\). An arc-transitive graph is said to be \(2\)-geodesic transitive if its automorphism group is transitive
on the set of \(2\)-geodesics. In this talk we will introduce the classification of \(2\)-geodesic transitive graphs of order \(p^n\)
for each prime \(p\) and \(n\leqslant 3\).
