  Let S(n) be the symmetric group on n points. A subset S of S(n) is
intersecting if for any pair of permutations \pi, \sigma in S there is a point
i in {1,...,n} such that \pi(i)=\sigma(i). Deza and Frankl \cite{MR0439648}
proved that if S a subset of S(n) is intersecting then |S| \leq (n-1)!.
Further, Cameron and Ku \cite{MR2009400} show that the only sets that meet this
bound are the cosets of a stabilizer of a point. In this paper we give a very
different proof of this same result.
