论文摘要
我们用$ m_ {1} = 4 $对Q-Polynomial协会方案进行分类，这些方案与最近的社区关系是部分度量的。如果$ r_2 $的方案图完全是$ r_1 $的距离-2 $的距离2图，则关联方案是根据关系图的部分度量。
We classify the Q-polynomial association schemes with $m_{1} = 4$ which are partially metric with respect to the nearest neighbourhood relation. An association scheme is partially metric with respect to a relation $R_1$ if the scheme graph of $R_2$ is exactly the distance-2 graph of the scheme graph of $R_1$ under a certain ordering of the relations.
