Consider the labelled pentagon

_anonymous_0 1 1 2 2 1--2 3 3 2--3 4 4 3--4 5 5 4--5 5--1

For each of the following permutations, determine if the permutation is a symmetry of the pentagon in flatland, sphereland (3 dimenions), or if the transformation is never a symmetry.


  1. Where is the permutation \begin{pmatrix} 1&2&3&4&5\\1&2&3&4&5\end{pmatrix} a symmetry of the above figure, if at all?
