Above is an image of regular loops joined together at right angles.
What shape do we get after cutting along the dashed lines?
Details and Assumptions:
A half twist is a \(180^{\circ}\) rotation of one side of the paper before you stick them together.
We define a twisted loop to be a loop with a positive even number of half twists.
