| Research Abstract |
Through the investigations of completely regular codes of a graph not necessarily distance-regular, I reached a concept of completely regular clique graphs, and gave several evidence that it plays a key role in a classification of classical distance-regular graphs. In particular, a thorough investigation of thin completely regular clique graphs will imply a classification of thin Q-polynomial distance-regular graphs.
