(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

x^2 = sigma.

The permutation sigma = (1 2 6 7 5 3 4), a cycle of length seven.

Determine x!

3. The attempt at a solution

I have tried a few times but my attempts are totally wrong. I don't know where to start! :S

I found a similar problem in the textbook. They could, by just lookin at the problem, say that there is no x for that (in the book not the one above) particular type of permutation. How? :S
