摘要：Group theory is widely applied in physical sciences. Also there have been attempts to apply it to social sciences such as anthropology and psychology. Here, it is shown that some group structures can be acquired through reinforcement learning. A reduced residue class group emerged through learning, and the result is isomorphic to the Klein four-group, which is the structure taken up by some renowned social scientists. Extending this approach to cyclic groups is straightforward. This finding provides the basis for how the group can be implicitly learned by the human.
