WebMar 24, 2024 · For example, the dihedral group is a permutation group on 14 elements that can be generated by two elements corresponding to a reversal and a rotation, respectively. Therefore, any two such elements give a connected Cayley graph that has 14 nodes and 28 edges. WebApr 7, 2024 · 1 Answer. Yes, the cycle r = ( 1, 2, 3,..., n) is always a suitable element. To find an element s or order 2 such that s r s = r − 1, you can use this trick: D n is the group of isometries of a regular n -agon: if you draw a n -agon and you label the vertices clockwise with numbers { 1, 2,..., n }, you can think that your permutation r is the ...
