   Format: MarkdownItexIn the category-theoretic approach (moved from the previous ZFA page), do we have to require the each element of the sets to have an open stabilizer? This would correspond to requiring the sets in the classical permutation model to be hereditarily symmetric, rather than just being symmetric.

   Format: MarkdownItexIf we take a set in a permutation model, then it's elements would have open stabilizers, so I believe this should be reflected in the corresponding category. This also corresponds to the action of the group being continuous (if the set is given the discrete topology), which is by itself a natural thing to require if we are given a topological group.
