摘要

本文证明了参数为 (63,11,8,1,2) 的有向强规则图的存在性。我们构造了一对非同构的 dsrg(63,11,8,1,2)，其中一个是通过反转所有箭头从另一个得到的。这两个有向强规则图的全自形群都是 L2(8):3。

A construction of directed strongly regular graphs with parameters (63,11,8,1,2)

In this paper, we prove the existence of directed strongly regular graphs with parameters $(63, 11, 8, 1, 2)$ . We construct a pair of nonisomorphic dsrg(63,11,8,1,2), where one is obtained from the other by reversing all arrows. Both directed strongly regular graphs have $L_{2} (8) : 3$ as the full automorphism group.

期刊介绍： Discrete Mathematics provides a common forum for significant research in many areas of discrete mathematics and combinatorics. Among the fields covered by Discrete Mathematics are graph and hypergraph theory, enumeration, coding theory, block designs, the combinatorics of partially ordered sets, extremal set theory, matroid theory, algebraic combinatorics, discrete geometry, matrices, and discrete probability theory. Items in the journal include research articles (Contributions or Notes, depending on length) and survey/expository articles (Perspectives). Efforts are made to process the submission of Notes (short articles) quickly. The Perspectives section features expository articles accessible to a broad audience that cast new light or present unifying points of view on well-known or insufficiently-known topics.
