Parameters of Strongly Regular Graphs

Tables with parameters for strongly regular graphs, with columns for: existence; number of vertices (v); valency (k); number of common neighbours of two adjacent vertices (λ); number of common neighbours of two nonadjacent vertices (μ); positive eigenvalue with multiplicity (rf); negative eigenvalue with multiplicity (sg); comments (undocumented at present).

本数据集为包含强正则图（strongly regular graphs）参数的表格，其各列依次为：存在性；顶点数（v）；度（valency，k）；相邻两顶点的公共邻点数（λ）；非相邻两顶点的公共邻点数（μ）；带重数的正特征值（rf）；带重数的负特征值（sg）；备注（目前暂无相关文档记录）。
