本文提供了一个从有限群的传递作用求真实的或复射影空间中点的良好排列的通用程序。在许多情况下,这些布置在最大化最小距离的意义上是最佳的。在重点讨论盖尔芬德对的特殊情况之前,我们先从一般的舒里安关联方案的角度介绍我们的程序。值得注意的是,我们的计划统一了各种现有的包装与迄今为止不同的建设。此外,我们利用我们的程序来构建第一个已知的无限族的等角线海森堡对称。
We provide a general program for finding nice arrangements of points in real or complex projective space from transitive actions of finite groups. In many cases, these arrangements are optimal in the sense of maximizing the minimum distance. We introduce our program in terms of general Schurian association schemes before focusing on the special case of Gelfand pairs. Notably, our program unifies a variety of existing packings with heretofore disparate constructions. In addition, we leverage our program to construct the first known infinite family of equiangular lines with Heisenberg symmetry.
