Abstract: The topological entropy of a crazy dynamic system with ΣN×S1 as the basic space is investigated, and its range is pointed out: lg N~2lg N. Moreover, a more exact result is given when the rotation maps occur in the fiber maps.

Key words: crazy dynamics, topological entropy, (n,ε)-spanning sets, fiber maps
