Distance-regular extensions of strongly regular graphs with eigenvalue 2 (Q1945184)

Let \(\Gamma\) be a strongly regular graphs with parameters \((100,36,14,12)\), \(G = \mathrm{Aut}(\Gamma)\), \(g\) be an element of simple order \(P\) from \(G\), and \(\Omega = \mathrm{Fix}(g)\). In this paper, the structure and properties of \(\Omega\) are determined completely. Then further specific structures and properties of the graph \(\Gamma\) are given. The results are interesting and meaningful.
