The answer is *yes*, and in fact the following more general result holds. >**Theorem.** Let $\mathbf{a}, \, \mathbf{b}, \, \mathbf{c}$ be three recursively enumerable degrees of unsolvability (i.e., Turing degrees) with $\mathbf{a} \leq \mathbf{b}$ and $\mathbf{a} \leq \mathbf{c}$. Then there exists a finitely presented group $L$ such that > - the word problem for $L$ is of degree $\mathbf{a};$ - the power problem for $L$ is of degree $\mathbf{b};$ - the order problem for $L$ is of degree $\mathbf{c}.$ See D. J. Collins: *The word, power and order problems in finitely presented groups*, in Studies in Logic and Fundations of Mathematics **71** (*Word Problems*), North-Holland (1973).
