报告摘要：

A Steiner system S(t, k, v) is a pair (X, B), where X is a v-set and B is a set of k-subsets of X (called blocks) such that every t-subset of X is contained in a unique block. An S(3, 4, v) is called a Steiner quadruple system of order v, briefly an SQS(v). A cyclic Steiner quadruple system, briefly CSQS(v), is an SQS (X, B) of order v and with a cyclic group of automorphisms that acts regularly on X. This talk is to present a survey for the research on CSQSs including construction methods and classification results.
