1. Construct a Cayley table for the group of symmetries of a square, write each element as a permutation. Label each vertex of the square by the numbers 1,2,3,4 clockwise, label the upper left corner by 1. For example the 90°-rotation should be 1 2 3 234 1). Determine, with proof, whether or not this group is abelian. Call this group D
