2. Given a regular n-gon, let r be a rotation of it by 2π/n radians. This time, assume that we are not allowed to flip over the n-gon. These n actions form a group denotecd (a) Draw a Cayley diagram for Cn for n-4, n-5, and n-6 (b) For n 4, 5, 6, find all minimal generating sets of C.· [Note: There are minimal generating sets of of size 2.] (c) Make a conjecture of what integers k does C,-〈rk〉 for a general fixed integer n ix svinne tries of an equilateral triangle 쇼 form a group 3. As we saw in lecture, the s denoted Ds -{e,r, r2,f,rf,r^f], where r is a 120 clockwise rotation and f is a flip about a vertical axis (which fixes the top corner). Since and f suffice to generate all six of these symmetries, we write D,-(nf) (a) Let g be the reflection of the triangle that fixes the lower-left corner. Which of the six actions in D3 is g equal to? Which action is fg? (b) Write all 6 actions of D3 using only f and g. Draw a Cayley diagram using f and g as generators (c) To generate D3, we need at least 2 actions. It is not difficult to show that if we have 3 generators, then one of them is unnecessary. Find all minimal generating sets of Ds e,r, r2,f,rf,r2 f); note that all of them should have exactly two actions. Do not use qa in this list
