"Webto deﬁne the Frenet frame, a condition (a non-degenerate condition) is needed. In general, the parallel curve does not satisfy these conditions. It is well-known that the Bertrand curves of regular curves do not exist under a condition in [19, 21]. In [20], they consider the condition of the Mannheim curves of regular curves.
