Steiner system

A Steiner system is a specific type of combinatorial design that relates to the arrangement of points and subsets of those points. More formally, a Steiner system \( S(t, k, n) \) is defined by three parameters \( t \), \( k \), and \( n \), where: - \( n \) is the total number of points. - \( k \) is the size of each subset (often called a block).
