组合设计的计数和构造
Enumeration and Construction of Combinatorial Configurations
【摘要】 给出了(b,v,r,k,λ)组态及(v,k,λ)组态的个数,r×n拉丁长方的个数,k-1个相互正交的n阶拉丁方组的个数的几个精确计算公式.并将(b,v,r,k,λ)及(v,k,λ)组态的存在及构造问题转化为判断和寻找一个数论问题的非负整数解的问题.
【Abstract】 In this paper, we shall give some explicit formulas for calculating the number of the (b,v,r,k,λ)- configurations,(v,k,λ)- configurations,r×n Latin rectangle and k-1 orthogonal Latin squares by means of Wang theorem(i.e.Lemma1) .
