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

The rectangle would appear thus: R0 MA453Fall2008walther.png

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.
