Zusammenfassung:We solve generalizations of Hubbard's twisted rabbit problem for analogues of the rabbit polynomial of degree \(d\geq 2\). The twisted rabbit problem asks: when a certain quadratic polynomial, called the Douady Rabbit polynomial, is twisted by a cyclic subgroup of a mapping class group, to which polynomial is the resulting map equivalent (as a function of the power of the generator)? The solution to the original quadratic twisted rabbit problem, given by Bartholdi--Nekrashevych, depended on the 4-adic expansion of the power of the mapping class by which we twist. In this paper, we provide a solution that depends on the \(d^2\)-adic expansion of the power of the mapping class element by which we twist.
