For prime powers q and q+ε where ε{1,2}, an affine resolvable design from Fq and Latin squares from Fq+ε yield a set of symmetric designs if ε=2 and a set of symmetric group divisible designs if ε=1. We show that these designs derive commutative association schemes, and determine their eigenmatrices.

从双素数幂,费马素数,梅森素数获得的交换关联方案

对于素数qq+ε 哪里 ε{1个2},来自的仿射可分辨设计 Fq 和来自的拉丁方 Fq+ε 产生一组对称设计,如果 ε=2 和一组对称的组可整除设计,如果 ε=1个。我们表明,这些设计导出了交换关联方案,并确定了它们的本征矩阵。
