Writing Cayley tables for these two groups produces the same tables that are a match further demonstrates the validity of this reasoning.

. The alternative assumption ab d results in a homomorphism. Let r be counterclockwise rotation by 273 and let s be the flip that leaves A fixed and exchanges B and C. However by reference to the table acb db a while a cb ad b.

Therearethreerotations s s s A C B R-0 s s. R 1 and r 2 denote counterclockwise rotations by 120 and 240 respectively and s 0 s 1 and s 2 denote reflections across the three lines shown in the adjacent picture. And so geometrically fr is a flip over the axis through the bottom most left-side vertex to be precise.

Let f be the flip over the vertical axis. The following Cayley table shows the effect of composition in the group D 3 the symmetries of an equilateral triangler 0 denotes the identity. The matrix representation is given by R 0 1 0 0 1.

The rest of the table follows as a Latin square. Share answered Sep 27 2016 at 1037 Nex 3634 1 10 23 Add a comment. Similarly there is purple edge from x to y if x 4 y.

From column 1 to column 6. We also look at Cayle. What does it mean for two group elements to be conjugate.

The command setlengthextrarowheight 3pt adds some extra row height how surprising. Draw an equilateral triangle and label the vertices with the letters A B and C. In particular we see that R 0 is the identity R 1 i R n i and S 1 i S i.

A Besides the identity D3 has three elements of order 2 b ab and a2 b and two elements of order 3 a and a2. Also note that both f and fr are involutions. It is a central tool in combinatorial and geometric group theory.
