In the first 11 days of the superoutburst, the early superhumps with the period of 0.056383d were found. In days 13-23 of the superoutburst, the ordinary superhumps with the period of 0.05713d were exposed. They were replaced by late superhumps with the period of 0.056d in days 24-33 of the superoutburst. After one month, the dwarf nova returned to its pre-outburst state. A list of known WZ Sge-type dwarf novae, including suspected ones, is presented. We determined a mean value of superhump period excess for WZ Sge-type objects as ε=0.019±0.003. The multicolour photometry of the field stars enables us to conclude that there is no appreciable interstellar extinction in the direction of V466 And. Description: Most of our UBV(RI)C CCD observations were taken with the SBIG ST10-XME camera mounted in the Newton focus of the 0.5m (f/5) reflector at the Stara Lesna Observatory. Further CCD observations were taken with the Apogee-47p and Pictor-416 cameras mounted in the Cassegrain focus of the 0.6m (f/12.5) reflector and 0.5m Maksutov (f/4.0) telescope at the Crimean Laboratory of the Sternberg Astronomical Institute. We also used the 0.6m telescope Zeiss-600 of the Terskol Observatory (in Caucasus) equipped with a CCD camera (the PixelVision Vienna with a 1024x1024 array and pixel size 24 micron).
