A non-square rectangle is depicted.
a. How many symmetries are there? What are they? Feel free to label them with whatever notation you like, but clearly describe what they do (reflect, rotate) and give their corresponding permutations.
b. Create a Cayley table for your group of symmetries.
c. Does your group behave more like like ℤ₄ or ℤ₂ % ℤ₂? Explain. It may help to create Cayley tables for ℤ₄ and ℤ₂ % ℤ₂.
