category of large families of sets and bijections

Notation (Setbij)I(\Set_{\bij})^I Objects families of sets (Xi)i∈I(X_i)_{i \in I} indexed by a collection II that is not essentially small Morphisms families of bijections Related SetI\Set^I, Setbij\Set_{\bij}

This is the core groupoid of SetI\Set^I. It provides an example of a groupoid that is not locally essentially small.
