    "abstract": "We point out that the N=4 supersymmetric KdV hierarchy, when written through\nthe prepotentials of the bosonic chiral and antichiral N=2 supercurrents,\nexhibits a freedom related to the possibility to choose different gauges for\nthe prepotentials. In particular, this implies that the Lax operator for the\nN=4 SKdV system and the associated realization of N=4 supersymmetry obtained in\nsolv-int/9802003 are reduced to the previously known ones. We give the\nprepotential form of the `small\u0027 N=4 superconformal algebra, the second\nhamiltonian structure algebra of the N=4 SKdV hierarchy, for two choices of\ngauge.",
