@inproceedings{Jin2022TwoarctransitiveB, title={Two-arc-transitive bicirculants}, author={Wei Jin}, year={2022} }

. In this paper, we determine the class of ﬁnite 2-arc-transitive bicirculants. We show that a connected 2-arc-transitive bicirculant is one of the following graphs: C 2 n where n > 2, K 2 n where n > 2, K n,n where n > 3, K n,n − n K 2 where n > 4, B (PG( d − 1 , q )) and B ′ (PG( d − 1 , q )) where d ≥ 3 and q is a prime power, X 1 (4 , q ) where q ≡ 3 (mod 4) is a prime power, K 2 d q +1 where q is an odd prime power and d ≥ 2 dividing q − 1, AT Q (1 + q, 2 d ) where d | q − 1 and d ∤ 1 2…

### A classification of pentavalent arc-transitive bicirculants

- Mathematics

A bicirculant is a graph admitting an automorphism with two cycles of equal length in its cycle decomposition. A graph is said to be arc-transitive if its automorphism group acts transitively on the…

This paper gives a classification of all primitive affine 2-arc transitive graphs, and all finite 'bi-primitive' affine 1-arctransitive graphs such that the stabilizer of the bipartition of the vertices is primitive on each part of the antipartition.

### Strongly Regular Semi-Cayley Graphs

- Mathematics

We consider strongly regular graphs Γ = (V, E) on an even number, say 2n, of vertices which admit an automorphism group G of order n which has two orbits on V. Such graphs will be called strongly…

Let X be a connected non-normal 4-valent arc-transitive Cayley graph on a dihedral group Dn such that X is bipartite, with the two bipartition sets being the two orbits of the cyclic subgroup within…

### Locally s‐distance transitive graphs

It is proved that, for s � 2, a nondegenerate, nonbasic graph in the class is either a complete multipartite graph, or a normal cover of a basic graph, and that, apart from the complete bipartite graphs, each basic graph admits a faithful quasiprimitive action on each of its (1 or 2) vertex orbits.

### Classification of Symmetric Tabačjn Graphs

- MathematicsGraphs Comb.

The Tabačjn graphs are introduced, a family of pentavalent bicirculants which are a natural generalization of generalized Petersen graphs obtained from them by adding two additional perfect matchings between the two orbits of a semiregular automorphism.

This note constructs bipartite 2-walk-regular graphs with exactly 6 distinct eigenvalues as incidence graphs of group-divisible designs with the dual property, and shows that they are 2-arc-transitive dihedrants.
