In this paper, some recent results on the numerical ranges of composition operators on the Hardy space are presented. Also, we show that the matrix representation of a self-inverse composition operator on the Hardy space with respect to the Guyker\\\\s basis is a block Toeplitz operator, and by using this representation, we determine the shape of the numerical range of such operators.
