Given any nonempty string X of length n, a factor W of X is called a cyclic cover if every position of X belongs to an occurrence of a cyclic shift of W. Two cyclic covers are distinct if one is not a cyclic shift of the other. Webthe cyclic branched covers are insensitive to the subtler structure of transverse knots. While we found no examples of non-contactomorphic branched covers, we are able to answer Question 1.1 positively in many special cases. In particular, we show that branched cyclic covers of any degree are contactomorphic for all examples of Birman– the stage line wells fargo
