COMPOSITE KNOTS TRIVIALIZED BY TWISTING
Masakazu Teragaito · Journal of Knot Theory and Its Ramifications · 1992
Some composite knots are known to be trivialized by twisting. However, the bridge index of the prime factors in known examples is two. In this note, for any integer n ≥ 1 we will construct composite knots which can be trivialized by twisting and which consist of two prime factors with bridge index greater than n.
