   Format: MarkdownItexInteresting. I thought we already had cited some work by Nora on this matter --- since she has been thinking about this 2-group approach to the Monster for a long time now, if I recall correctly --- but now I can't find it. A hint is in Example 6.5 on [p. 13](https://arxiv.org/pdf/1406.7046#page=13) of "Categorical Tori".
