Webective symmetry. The dihedral group that describes the symmetries of a regular n-gon is written D n. All actions in C n are also actions of D n, but there are more than that. The group D n contains 2n actions: n rotations n re ections. However, we only need two generators. Here is one possible choice: 1. r =counterclockwise rotationby 2ˇ=n ... WebTranscribed Image Text: 6 Let G= Dº be the dihedral group of order 12, H be the subgroup of G generated by R120 where R₁20 is a counterclockwise rotation of 120°, and K be the subgroup of G generated by R180L where L is a reflection. 1. List all elements of G, H, K 2. What is the order of L R60 in G? 1. WebThe dihedral group D3 = {e,a,b,c,r,s} is of order 6. Geometrically it represents the symmetries of an equilateral triangle; see Fig. 1 below. It is isomorphic to the group S3 of all permutations of three objects. • Multiplication table.
