Using the classification of transitive groups of degree n, for $2\le n\le 48$, we classify the Schurian association schemes of order n, and as a consequence, the transitive groups of degree n that are 2-closed. In addition, we compute the character table of each association scheme and provide a census of important properties. Finally, we compute the 2-closure of each transitive group of degree n, for $2\le n\le 48$. The results of this classification are made available as a supplementary database.

小型 Schurian 协会计划的普查

使用n次传递群的分类，对于$2\le n\le 48$，我们对n阶 Schurian 关联方案进行分类，因此，n次传递群是 2-闭的。此外，我们计算每个关联方案的字符表并提供重要属性的普查。最后，我们计算每个n次传递群的 2-闭包，对于$2\le n\le 48$。该分类的结果作为补充数据库提供。
