   Format: MarkdownItexSorry, I am being dense. I could swear that we once wrote an entry on classifying toposes for $G$-torsors, their various equivalent incarnations and properties. But either I just dreamed this, or I forget in which entry we did this. I don't see it at [[classifying topos]], and don't see it linked there. Does anyone remember the entry that I have in mind here?
