It has been clarified that charged excitation known 218 a skyrmion exists arotrnd the ferrotnagnetic ground state at the Landatr level filling factor v = I/q, where q is an odd integer. Aninfinite sized skyrrnion is realized in the absence of the spin-Zeeman splitting or f'or double-Iatyered systetns. Analytical forna of the wave ftrnction is identified at v = l and v :: l /3 tlarotughexact diagonalization of tlae Hamiltonian for finite sized spherical systerns. It is clarified th?tt theskyrrnion wave ftrnctions at v = 1 and v : 173 are qtralitatively difl'erent: they are not relatedby the couaaposite ['errmion transf'orraaation. Long-range behavior of the skyrrnion wave ftmnctionaroxrnd v : 1 is shown to be consistent with the seutaiclassical picture of the skyrunion,
