Finding a permutation $ \alpha $ given $ \alpha^4 $

151 Views Asked by At

I have the following question:

Find a permutation $\alpha ∈ S_7 $ such that $\alpha^4 = (2 1 4 3 5 6 7)$. Is $\alpha$ unique?

How should I go about this? I've tried a few different trial and error type solutions but to no avail.

Thanks
