Two-arc-transitive two-valent digraphs of certain ordersBerčič, Katja (Avtor) Potočnik, Primož (Avtor) graphdigrapharc-transitiveorderThe topic of this paper is digraphs of in-valence and out-valence 2 that admit a 2-arc-transitive group of automorphisms. We classify such digraphs that satisfy certain additional conditions on their order. In particular, a classification of those with order ▫$kp$▫ or ▫$kp^{2}$▫ where ▫$k \leq 14$▫ and ▫$p$▫ is a prime can be deduced from the results of this paper.20162016-08-03 04:07:07Neznano8321sl
