Moreover, we tackle the problem of computing the maximum . that makes two given languages .-congruent. This problem is .-complete for two regular languages, and undecidable for context-free languages.

Then, we characterize the edit-distance interior languages and present a proper hierarchy with respect to the radius of operations. The family of edit-distance interior languages is closed under intersection, but not closed under union, complement and catenation.
