摘要
假设自同构群 在有限广义六边形或八边形 上旗传递地作用,并且假设该作用在点集和线集上都是本原的。我们证明了 是 Lie 型的几乎单群,即 的基柱是一个单 Chevalley 群。

评论
forgot to upload the appendices in version 1, and this is rectified in version 2. erased cross-ref keys in version 3. Minor revision in version 4 to implement the suggestion by the referee (new section at the end, extended acknowledgment, simpler proof for Lemma 4.2)
