摘要:  Let Γ be a distance regular cover of (k +1)-clique with λ = μ. If local subgraphs are strongly regular with parameters (v’, k’, λ’, μ’), then v’= k, k’= λ, and b1= k − λ − 1 = (r − 1)μ, so k’= λ devides v’− 1. It is determined parameters of strongly regular graphs with at most 1000 vertices, which may be local subgraphs in distance regular cover of clique with λ = μ. It is classified arc-transitive distance regular cover of clique with λ = μ with local subgraphs, whose parametrs belongs to our list.
