Let G be the group of symmetries of an equilateral triangle. Recall that G has 6 elements: the identity symmetry e, two nontrivial rotations, and three flips. Let r be be a rotation 120o counter-clockwise, so that the two nontrivial rotations in G are r and r2. To keep track of the flips, let A be the lower left vertex of the triangle, B the top vertex, and C the lower right vertex of the triangle; and write fa, fb,...
