A noncomplete graph Γ is said to be (G, 2)‐distance transitive ifGis a subgroup of the automorphism group of Γ that is transitive on the vertex set of Γ, and for any vertexuof Γ, the stabilizer is transitive on the sets of vertices at distances 1 and 2 fromu. This article investigates the family of (G, 2)‐distance transitive graphs that are not (G, 2)‐arc transitive. Our main result is the classification of such graphs of valency not greater than 5. We also prove several results about (G, 2)‐distance transitive, but not (G, 2)‐arc transitive graphs of girth 4.
