论文摘要
Penttila和Williford从广义的四边形构建了一个$ 4- $的类协会方案，并带有双重子键符号。我们表明，具有适当参数并满足最大集团的某些假设的关联方案必须是Penttila-Williford方案。
Penttila and Williford constructed a $4-$class association scheme from a generalized quadrangle with a doubly subtended subquadrangle. We show that an association scheme with appropriate parameters and satisfying some assumption about maximal cliques must be the Penttila-Williford scheme.
