# HW2, Chapter 1 problem 13, Discussion, MA453, Prof. Walther

Problem Statement:

**Can somebody please write the problem statement?**

If you name the vertices of the four rectangles A, B, C, and D.

The rectangle would appear thus:

The rectangle would have four transformations:

Rotation of 0º (or 360º) : $ R_{0} $

Rotation of 180º: $ R_{180} $

Flip About a Horizontal Axis: $ H $

Flip About a Vertical Axis: $ V $

From this, the Cayley table can easily be constructed.
