The N=4 SU (2)k superconformal algebra has the global automorphism of SO(4)≈ SU ((2)× SU ((2) with the left factor as the Kac-Moody gauge symmetry. As a consequence, an infinite set of independent algebras labeled by ρ corresponding to the conjugate classes of the outer automorphism group SO (4)/SU(2)= SU (2) are obtained à la Schwimmer and Seiberg. We construct Feigin-Fuks representations with the ρ parameter embedded for the infinite set of the N =4 nonequivalent algebras. In our construction the extended global SU(2) algebras labeled by ρ are self-consistently represented by fermion fields with appropriate boundary conditions.
