We shall consider the small gauge symmetries of Cartan Chern-Simons theory and argue that they coincide of a gauge theory and the diffeomorphism group of gravity are very different beasts. of first-order gravity by small symmetries and large gauge transformations.	./cache/work_3gy4shpuufetvircmnlly2kqoi.pdf	./txt/work_3gy4shpuufetvircmnlly2kqoi.txt
