Permutation and cycles
Let \([n]\) be the set \(\{1,2,...,n\}\) (we call each element a vertex) and
a permutation of \([n]\) be \(\pi=[\pi(1),\pi(2),\cdots,\pi(n)]\), i.e.,
denote \(\pi(x)=y\) the fact that in a permutation, position \(x\) has vertex \(y\).
There are \(n!\) possible permutations of \([n]\).
