A construction is given of a 4-valent 1/2-arc-transitive graph with vertex stabilizer isomorphic to dihedral group ▫$D_S$▫. The graph has 10572 vertices and is the first known example of a 4-valent 1/2-arc-transitive graph with nonabelian vertex stabilizer.

We present some new discoveries about graphs that are half-arc-transitive (that is, vertex- and edge-transitive but not arc-transitive). These include the recent discovery of the smallest half-arc-transitive 4-valent graph with vertex-stabiliser of order 4, and the smallest with vertex-stabiliser of ...

Let ▫$X$▫ be a finite vertex-transitive graph of valency ▫$d$▫, and let ▫$A$▫ be the full automorphism group of ▫$X$▫. Then the arc-type of ▫$X$▫ is defined in terms of the sizes of the orbits of the stabiliser ▫$A_v$▫ of a given vertex ▫$v$▫ on the set of arcs incident with ▫$v$▫. Such an orbit is ...

Oznake:
An orientably-regular map is a cellular embedding of a graph or multigraph in an orientable-surface, with the property that the group of orientation- and incidencepreserving automorphisms has a single orbit on the arcs (ordered edges) of the embedding. I will describe a recent computer-assisted d ...
