WebSOLUTIONS OF SOME HOMEWORK PROBLEMS MATH 114 Problem set 1 4. Let D4 denote the group of symmetries of a square. Find the order of D4 and list all normal subgroups in D4. Solution. D4 has 8 elements: 1,r,r2,r3, d 1,d2,b1,b2, where r is the rotation on 90 , d 1,d2 are flips about diagonals, b1,b2 are flips about the lines joining the … WebMay 12, 2024 · Do the translation first. The rule is: T(3,-1) (x,y) -----> (x+3,y-1) Do the rotation second. Assuming it's about the origin (O), the rule is:

WebMar 24, 2024 · The dihedral group D_6 gives the group of symmetries of a regular hexagon. The group generators are given by a counterclockwise rotation through pi/3 radians and reflection in a line joining the midpoints of two opposite edges. If x denotes rotation and y reflection, we have D_6=.
