A Cayley table lists the results of all such compositions possible. For example, rotating by 270° clockwise (⁠ r 3 ⁠) and then reflecting horizontally (⁠ f h ⁠) is the same as performing a reflection along the diagonal (⁠ f d ⁠). Using the above symbols, highlighted in blue in the Cayley table: f h ∘ ∘ r 3 = f d .
