Many experts have been doing research on characterizations of congruence n-permutable varieties in many different ways. In 1973 Hagemann and Mitschke, generalizing Maltsev conditions, provided a simple and nice characterization of congruence n-permutable varieties. We offer our own approach to the characterization of congruence n-permutable varieties, inspired by the Kearnes/Tschantz lemma.
