差分法与费列罗对
Difference Methods and Ferrero Pairs
摘要：
本文给出了一种由有限群G和G上的自同构群Φ构造BIB-design的方法，使得|Φ（x）| = |Φ|对于G中的所有x，x <> 0。利用差族概念的推广，我们可以统一几个以前的平面近环的BIB-designs的构造。
英文摘要：
We present a construction method of BIB-designs from a finite group G and a group of automorphisms Φon G such that |Φ(x)| = |Φ| for all x in G, x <> 0. By using a generalization of the concept of a difference family we can so unify several previous constructions of BIB-designs from planar near-rings.
